    * medium-density fibreboard (MDF)

"MDF is an engineered wood product made by breaking down hardwood or softwood residuals into wood fibres, often in a defibrator, combining it with wax and a resin binder, and forming it into panels by applying high temperature and pressure.[1] MDF is generally more dense than plywood. It is made up of separated fibres, but can be used as a building material similar in application to plywood. It is stronger, and more dense, than particle board.[2]"

    * bamboo

"Bamboo, like true wood, is a natural building material with a high strength-to-weight ratio useful for structures.[7]"

    * glulam

Glued laminated timber, also abbreviated glulam, is a type of structural engineered wood product constituted by layers of dimensional lumber bonded together with durable, moisture-resistant structural adhesives. In North America, the material providing the laminations is termed laminating stock or lamstock
By laminating a number of smaller pieces of lumber, a single large, strong, structural member is manufactured from smaller pieces. These structural members are used as vertical columns, horizontal beams, and arches. Glulams are readily produced in curved shapes and are available in a range of species and appearances.[1] Connections are usually made with bolts or steel dowels and steel plates. 
Glulam optimizes the structural values of wood. Because of their composition, large glulam members can be manufactured from a variety of smaller trees harvested from second-growth forests and plantations. Glulam provides the strength and versatility of large wood members without relying on the oldgrowth-dependent, solid-sawn timbers. [2]: 3  As with other engineered wood products, it reduces the overall amount of wood used when compared to solid-sawn timbers by diminishing the negative impact of knots and other small defects in each component board. 
Glulam has much lower embodied energy than reinforced concrete and steel, although it entails more embodied energy than solid timber. However, the laminating process allows the timber to be used for much longer spans, heavier loads, and more complex shapes than reinforced concrete or steel. Glulam is one tenth the weight of steel and one sixth the weight of concrete; the embodied energy to produce it is one sixth of that for a comparable strength of steel.[3] Glulam can be manufactured to a variety of shapes, so it offers architects artistic freedom without sacrificing structural requirements. 
Glulam arches of the Sheffield Winter Garden
The high strength and stiffness of laminated timbers enable glulam beams and arches to span large distances without intermediate columns, allowing more design flexibility than with traditional timber construction. The size is limited only by transportation and handling constraints.[4]

    * stainless steel

Stainless steel[1][2][3]: 276  is any of a group of ferrous alloys that contain a minimum of approximately 11% chromium,[4]: 3 [5] a composition that largely inhibits the iron from rusting and provides heat-resistant properties.[4]: 3 [5][6][7][8] Different types of stainless steel include the elements carbon, nitrogen, aluminium, silicon, sulfur, titanium, nickel, copper, selenium, niobium, and molybdenum.[4]: 3  Specific types of stainless steel are often designated by their AISI three-digit number, e.g., 304 stainless.[9] The ISO 15510 standard lists the chemical compositions of stainless steels of the specifications in existing ISO, ASTM, EN, JIS, and GB standards in a useful interchange table.[10]
Stainless steel's resistance to rusting results from the presence of chromium in the alloy, which forms a passive film that protects the underlying material from corrosion attack, and can self-heal in the presence of oxygen.[4]: 3  Corrosion resistance can be increased further by the following means: 
  • increase chromium content to more than 11%[5]
  • add nickel to at least 8%[5]
  • add molybdenum (which also improves resistance to pitting corrosion)[5]
The addition of nitrogen also improves resistance to pitting corrosion and increases mechanical strength.[5] Thus, there are numerous grades of stainless steel with varying chromium and molybdenum contents to suit the environment the alloy must endure.[11]

Stainless steels can be classified by their crystalline structure into five main types: austenitic, ferritic, martensitic, duplex, and precipitation hardened.[1] Martensitic stainless steel is a specific type of stainless steel alloy that can be hardened and tempered through multiple ways of aging/heat treatment.

### harvesting in the desert

    * adobe

Adobe (/əˈdoʊbi/ (listen);[1] Spanish pronunciation: [aˈðoβe]) is a building material made from earth and organic materials. Adobe is Spanish for 'mudbrick', but in some English-speaking regions of Spanish heritage the term is used to refer to any kind of earthen construction. Most adobe buildings are similar in appearance to cob and rammed earth buildings. Adobe is among the earliest building materials, and is used throughout the world. 

    * super adobe / hyperadobe


From Superadobe, created by the Iranian Nader Khalili, was developed  Hyperadobe by Fernando Pacheco of EcoOca in Brazil. The big difference between the two is that Superadobe uses woven polypropylene bags with barbed wire between the layers, whereas Hyperadobe uses a knit raschel, the same material used in packaging fruit. This leads to less cost compared to the poly bags. 

    * bitumen/asphalt
$$$$ category
Asphalt, also known as bitumen (UK: /ˈbɪtjʊmɪn/, US: /bɪˈtjuːmən, baɪ-/),[1] is a sticky, black, highly viscous liquid or semi-solid form of petroleum. It may be found in natural deposits or may be a refined product, and is classed as a pitch.
The primary use (70%) of asphalt is in road construction, where it is used as the glue or binder mixed with aggregate particles to create asphalt concrete. Its other main uses are for bituminous waterproofing products, including production of roofing felt and for sealing flat roofs.[4]
In material sciences and engineering, the terms "asphalt" and "bitumen" are often used interchangeably to mean both natural and manufactured forms of the substance, although there is regional variation as to which term is most common


A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel (aggregate) together
Cements used in construction are usually inorganic, often lime or calcium silicate based, which can be characterized as non-hydraulic or hydraulic respectively, depending on the ability of the cement to set in the presence of water (see hydraulic and non-hydraulic lime plaster). 

    * non-hydraulic cement

Non-hydraulic cement does not set in wet conditions or under water. Rather, it sets as it dries and reacts with carbon dioxide in the air. It is resistant to attack by chemicals after setting. 

    * hydraulic cement

Hydraulic cements (e.g., Portland cement) set and become adhesive due to a chemical reaction between the dry ingredients and water. The chemical reaction results in mineral hydrates that are not very water-soluble and so are quite durable in water and safe from chemical attack. This allows setting in wet conditions or under water and further protects the hardened material from chemical attack. The chemical process for hydraulic cement was found by ancient Romans who used volcanic ash (pozzolana) with added lime (calcium oxide). 

    * magnesium cement

    * concrete

Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. In the past, limebased cement binders, such as lime putty, were often used but sometimes with other hydraulic cements, such as a calcium aluminate cement or with Portland cement to form Portland cement concrete (named for its visual resemblance to Portland stone).[2][3] Many other non-cementitious types of concrete exist with other methods of binding aggregate together, including asphalt concrete with a bitumen binder, which is frequently used for road surfaces, and polymer concretes that use polymers as a binder.

    * fiberglass

Other common names for fiberglass are glass-reinforced plastic (GRP),[1] glass-fiber reinforced plastic (GFRP)[2] or GFK (from German: Glasfaserverstärkter Kunststoff).
also see https://en.wikipedia.org/wiki/Fibre-reinforced_plastic

Glass(fiber) Reinforced Plastic (GRP) is a composite material that consists of a polymer matrix and glass fibers. The polymer matrix is usually an epoxy, vinylester, or polyester thermosetting resin. The resin brings the environmental and chemical resistance to the product, is the binder for the fibers in the structural laminate and defines the form of a GRP part. The glass fibers add strength to the composite. They may be randomly arranged, or conveniently oriented. The most common type of glass fiber used for GRP is E-glass, which is alumino-borosilicate glass. E-CR-glass (Electrical/Chemical Resistance) is also commonly used in applications that require particularly high protection against acidic corrosion.

    * spray foam / polyurethan foam ("PUR")

Spray foam is a chemical product created by two materials, isocyanate and polyol resin, which react when mixed with each other and expand up to 30-60 times its liquid volume after it is sprayed in place. This expansion makes it useful as a specialty packing material which forms to the shape of the product being packaged and produces a high thermal insulating value with virtually no air infiltration.

"Getting a smooth, blemish-free finish with oil-based polyurethane is within your grasp if you follow the steps in this article. Oil-based polyurethane varnish brings out the wood’s natural beauty or wood grain. Our 4-step approach shows you how to apply the varnish successfully. A good-quality natural-bristle brush, a reasonably dust-free, well ventilated space and some patience are all you need."


vs polyurea ???
Polyurea and polyurethane are copolymers used in the manufacture of spandex, which was invented in 1959. 

Polyurea has become a preferred long term solution for narrow boats. The traditional coating with bitumen, known as "blacking" is being replaced with the practice of polyurea coatings. The clearest advantage is that it is not necessary to reapply a coat every 3–4 years. It is thought that polyurea coatings last 25–30 years.[5]


aromatic or aliphatic (?)
Aromatic is generally used for black and darker colors, and is the least expensive option. 
Aliphatic can be a better option for colors because its color is more stable over time in ultraviolet light. It is produced with pure polyurethane, which drives up the cost approximately 35%. Aliphatic materials can be sprayed in a wide variety of colors, including metallic finishes. 

can be applied by rollers or spray-on !

    * insulative paint ("lizard skin")


Insulative paints, or insulating paints, claim to use a technology where a broad spectrum thermally reflective coating is applied to a specific type of micro-spheres to block heat radiation in a much larger or broader range of thermal energy (heat) to dissipate heat rapidly. This type of coated thermally reflective material (coated micro-sphere) reduces heat transfer through the coating with 90% of solar infrared radiation and 85% of ultraviolet radiation being radiated back from the coated surface.[citation needed]

    * tar

sometimes confused with bitumen/asphalt:
    "Colloquially, various forms of asphalt are sometimes referred to as "tar", as in the name of the La Brea Tar Pits, although tar is a different material.[5]"

Tar is a dark brown or black viscous liquid of hydrocarbons and free carbon, obtained from a wide variety of organic materials through destructive distillation. Tar can be produced from coal, wood, petroleum, or peat.[1]
Tar was used as seal for roofing shingles and tar paper and to seal the hulls of ships and boats. For millennia, wood tar was used to waterproof sails and boats, but today, sails made from inherently waterproof synthetic substances have reduced the demand for tar. Wood tar is still used to seal traditional wooden boats and the roofs of historic, shingle-roofed churches, as well as painting exterior walls of log buildings. Tar is also a general disinfectant.

    * thin film

A thin film is a layer of material ranging from fractions of a nanometer (monolayer) to several micrometers in thickness. The controlled synthesis of materials as thin films (a process referred to as deposition) is a fundamental step in many applications. A familiar example is the household mirror, which typically has a thin metal coating on the back of a sheet of glass to form a reflective interface. The process of silvering was once commonly used to produce mirrors, while more recently the metal layer is deposited using techniques such as sputtering. Advances in thin film deposition techniques during the 20th century have enabled a wide range of technological breakthroughs in areas such as magnetic recording media, electronic semiconductor devices, Integrated passive devices, LEDs, optical coatings (such as antireflective coatings), hard coatings on cutting tools, and for both energy generation (e.g. thin-film solar cells) and storage (thin-film batteries). It is also being applied to pharmaceuticals, via thin-film drug delivery. A stack of thin films is called a multilayer. 

    * shellac (natural lacquer)

Shellac (/ʃəˈlæk/)[1] is a resin secreted by the female lac bug on trees in the forests of India and Thailand. It is processed and sold as dry flakes and dissolved in alcohol to make liquid shellac, which is used as a brush-on colorant, food glaze and wood finish. Shellac functions as a tough natural primer, sanding sealant, tannin-blocker, odour-blocker, stain, and high-gloss varnish. Shellac was once used in electrical applications as it possesses good insulation qualities and it seals out moisture. Phonograph and 78 rpm gramophone records were made of it until they were replaced by vinyl long-playing records from the 1950s onwards. 
From the time it replaced oil and wax finishes in the 19th century, shellac was one of the dominant wood finishes in the western world until it was largely replaced by nitrocellulose lacquer in the 1920s and 1930s.

    * tyvek tape
Finish the building envelope with a superior seam tape – DuPont™ Tyvek® Tape. It helps to create a continuous building envelope system which keeps water and air out. Benefits can include not only better building durability but improved energy efficiency through reduced air leakage.  Tyvek® Tape is strong, easy to use, and highly waterproof. It is constructed of an oriented polypropylene film, coated with a specially formulated permanent acrylic adhesive to create the best adhesion between seam tape and DuPont™ Tyvek® weather barriers.  From a single family home to an office tower, air and water infiltration can make insulation significantly less effective, heating and air conditioning more costly. Tyvek® Tape contributes to energy efficiency by helping to seal the building envelope, which controls air flow and water intrusion in the wall assembly.

Super glue vs flexible adhesives
Super glue dries and cures in seconds, making it suitable for minor repairs like holes in the sole. For more extensive repairs, such as reattaching a shoe's sole, use a flexible adhesive like urethane rubber and let it cure. Always follow the manufacturer's drying and curing recommendations.

Flexible adhesives:
    * Neoprene Cement
        This glue can connect rubber, polyurethane, vinyl, cotton, leather and other synthetic and woven textiles. Like urethane shoe glue, neoprene cement is waterproof upon drying, making it an excellent choice for effectively sealing holes.
    * Urethane
        Urethane, sometimes known as urethane rubber, is a strong, waterproof adhesive that is resistant to heat and cold. It prevents your footwear from falling apart and is usually used to repair soles that have been detached from the shoe or severely damaged. It bonds the two halves of the shoe together with a powerful adhesive formula that stays flexible even after curing.

White gorilla glue is my go-to glue for everything. It cures in about an hour and usually stops foaming out in 30 minutes. I'm not sure where you live but if you are in an arid climate, pick up a small spray bottle from a dollar store and use some distilled water. Lightly spray your joint to be glued prior to applying the glue. To prevent the glue from foaming out where you do not want, simply apply tape to that area. You can use painter's tape for this and then remove it later. The foam will give long before the glue does. While this may take longer to dry, keep in mind that if you plan your build well, you can work on other parts while the previous part(s) are drying

It’s also a great choice for areas that are subject to extreme conditions – whether that’s temperature, traffic, or chemicals. Unlike epoxy flooring, MMA can be used in areas that reach sub-zero temperatures. This makes it a good option for food and beverage processing plants and pharmaceutical manufacturing sites. Methyl methacrylate is FDA and USDA compliant, as well as certified by the NSF. Given its tolerance to low temperatures, MMA can be used both inside and outside.

(Tribology = study of grease)

Tribology is the science and engineering of interacting surfaces in relative motion. It includes the study and application of the principles of friction, lubrication, and wear. Tribology is highly interdisciplinary. It draws on many academic fields, including physics, chemistry, materials science, mathematics, biology, and engineering. People who work in the field of tribology are referred to as tribologists.[1]
  • In total, ~23% of the world's energy consumption originates from tribological contacts. Of that, 20% is to overcome friction and 3% to remanufacture worn parts and spare equipment due to wear and wear-related. [...] 
  • Implementing advanced tribological technologies can also reduce global carbon dioxide emissions by as much as 1,460 million tons of carbon dioxide equivalent (MtCO2) and result in 450,000 million Euros cost savings in the short term. In the long term, the reduction could be as large as 3,140 MtCO2 and the cost savings 970,000 million Euros.

    * paint thinner

A paint thinner is a solvent used to thin oil-based paints or clean up after their use. Commercially, solvents labeled "Paint Thinner" are usually mineral spirits having a flash point at about 40 °C (104 °F),[not verified in body] the same as some popular brands of charcoal starter.[original research?]
Common solvents historically used as paint thinners include:[citation needed]
  • Mineral spirits (US)/White spirit (UK)
  • Acetone
  • Turpentine
  • Naphtha
  • Toluene
  • Methyl ethyl ketone (MEK)
  • Dimethylformamide (DMF)
  • 2-Butoxyethanol, or any of the other glycol ethers
Less common solvents used as paint thinner include:[1][failed verification]
  • Ethylbenzene
  • Xylene
  • n-Butyl acetate
  • Butanol



Lacquer thinner, also known as cellulose thinner, is usually a mixture of solvents able to dissolve a number of different resins or plastics used in modern lacquer.[1]
Previously, lacquer thinners frequently contained alkyl esters like butyl or amyl acetate, ketones like acetone or methyl ethyl ketone, aromatic hydrocarbons like toluene, ethers such as glycol cellosolves, and/or alcohols.[2]

The most common types of plaster/Powder mainly contain either gypsum, lime, or cement,[3]  but all work in a similar way.  The plaster is manufactured as a dry powder and is mixed with water to form a stiff but workable paste immediately before it is applied to the surface.  The reaction with water liberates heat through crystallization and the hydrated plaster then hardens.

Penetrating oil, also known as penetrating fluid, is very low-viscosity oil. It can be used to free rusted mechanical parts (such as nuts and bolts) so that they can be removed, because it can penetrate into the narrow space between the threads of two parts.  It can also be used as a general-purpose lubricant, a cleaner, or a corrosion stopper. Using penetrating fluids as  general-purpose lubricants is not advisable, because such oils are relatively volatile. As a result, much of the penetrating oil will evaporate in a short amount of time, leaving little residual lubricant. 
Other uses include: removing chewing gum and adhesive stickers, lessening friction on metal-stringed musical instruments, various gardening purposes and household repair tasks.

Kevlar is a heat-resistant and strong synthetic fiber, related to other aramids such as Nomex and Technora. Developed by Stephanie Kwolek at DuPont in 1965,[1][2][3] this high-strength material was used first commercially in the early 1970s as a replacement for steel in racing tires. Typically it is spun into ropes or fabric sheets that can be used as such or as an ingredient in composite material components. 

Kevlar has many applications, ranging from bicycle tires and racing sails to bulletproof vests, because of its high tensile strength-to-weight ratio; by this measure it is five times stronger than steel.[2] It also is used to make modern marching drumheads that withstand high impact.  It is used for mooring lines and other underwater applications.

Titanium: The fast-and-light choice
In 1999, the MSR product catalog declared: “You want light? You want strong? You want Titanium.” Indeed, titanium’s biggest advantage is its ultralight performance. Titanium is 45% lighter than steel and stronger than aluminum. It is the lightest cookware material you can buy before you must sacrifice strength. It’s also corrosion-resistant, offering great durability.
Titanium pots are ideal primarily for boiling water because they can be made with thin walls, and transfer heat very quickly. Like stainless steel pots, they tend to develop hot spots, making them less than ideal for cooking real meals. Titanium is favored by the truly fast-and-light crowd, who count their grams and opt for quick boil-only meals after a long, exhausting day.

* radiant barrier (like Reflectix)

A radiant barrier is a type of building material that reflects thermal radiation and reduces heat transfer. Because thermal energy is also transferred by conduction and convection, in addition radiation, radiant barriers are often supplemented with thermal insulation that slows down heat transfer by conduction or convection. 
A radiant barrier reflects heat radiation (radiant heat), preventing transfer from one side of the barrier to another due to a reflective, low emittance surface. In building applications, this surface is typically a very thin, mirror-like aluminum foil. The foil may be coated for resistance to the elements or for abrasion resistance. The radiant barrier may be one or two sided. One sided radiant barrier may be attached to insulating materials, such as polyisocyanurate, rigid foam, bubble insulation, or oriented strand board (OSB). Reflective tape can be adhered to strips of radiant barrier to make it a contiguous vapor barrier or, alternatively, radiant barrier can be perforated for vapor transmittance.

Blue stuff on bolts!

Thread-locking fluid or threadlocker is a thin, single-component adhesive, applied to the threads of fasteners such as screws and bolts to prevent loosening, leakage, and corrosion. 
Most thread-locking formulas are methacrylate-based and rely on the electrochemical activity of a metal substrate to cause polymerization of the fluid. Thread-locking fluid is thixotropic, which allows it to flow well over time, yet still resist shocks and vibrations. It can be permanent or removable; in the latter case, it can be removed with heat, for example. Typically, brands are color-coded to indicate strength and whether they can be removed easily or if they require heat for removal.

* gelcoat
Gelcoat or 'Gel Coat' is a material used to provide a high-quality finish on the visible surface of a fibre-reinforced composite. The most common gelcoats are thermosetting polymers based on epoxy or unsaturated polyester resin chemistry. Gelcoats are modified resins which are applied to moulds in the liquid state. They are cured to form crosslinked polymers and are subsequently backed with thermoset polymer matrix composites which are often mixtures of polyester resin and fiberglass, or epoxy resin which is most commonly used with carbon fibre for higher specific strength. 
In addition to any pigment a gelcoat will, if necessary, contain a thixotropic additive to assist its tenacity to vertical portions of the mould whilst it cures. 

nice resource
(fiberglass / gelcoat cracks repair)

You can't gelcoat or paint on a wax (styrene monomer) filled surface resin. The way the wax works is to float to the surface and create a seal from the air to let the gelcoat cure. If you abrade the wax off afterwards you can re gel or paint. Better to have a fully wax free surface to paint, no contamination, but it will still need some abrasion. 

Miktyri, you are right about the wax content in gelcoat. Gelcoat will not harden if it is exposed to the air, the wax rises to the surface and seals it during the curing process. No Wax is a good choice if you are laying up multiple coats, you don't have to remove the wax between coats. If you can seal the repair by placing a sheet of mylar or wax paper over the patch then the no-wax will work but if you can't you need to have the wax in the gelcoat to get it to cure. When I buy Gelcoat I normally get the no-wax varity and then get some of the wax additive so that I can make my choice when mixing up for the patch.

Carbon fibers or carbon fibres (alternatively CF, graphite fiber or graphite fibre) are fibers about         5 to 10 micrometers (0.00020–0.00039 in) in diameter and composed mostly of carbon atoms.[citation needed] Carbon fibers have several advantages including high stiffness, high tensile strength, low weight to strength ratio, high chemical resistance, high temperature tolerance and low thermal expansion.[citation needed] These properties have made carbon fiber very popular in aerospace, civil engineering, military, and motorsports, along with other competition sports. However, they are relatively expensive when compared with similar fibers, such as glass fibers or plastic fibers.[citation needed]

"Put some damming, alubutyl. Mine got to around 65-70db [from 80db]"

Alubutyl is the trade name for a self-adhesive film, which consists of self-adhesive butyl rubber and an aluminum carrier film . 
Alubutyl is used in a similar way to self-adhesive bitumen sealing strips and sheets for sound insulation in vehicles (anti-drumming mats) and behind sheet metal parts such as sinks, housing parts of large household appliances. Similar products with foil or fleece as carrier material are used for gluing and sealing joints in construction or for repairing gutters. 
This article or the following section is not adequately provided with supporting documents ( e.g. individual evidence ). Information without sufficient evidence could be removed soon. Please help Wikipedia by researching the information and including good evidence.
Alubutyl insulates a little better than bitumen, is lighter and easier to work with. However, bitumen is significantly cheaper to manufacture than alubutyl. 
The sound-absorbing effect is based on the mass (lowering the natural resonance frequency) and the plastic, vibration-damping consistency (avoidance of partial vibrations).

* hempcrete (and hemp materials at large)


Hempcrete or hemplime is biocomposite material, a mixture of hemp hurds (shives) and lime,[1] sand, or pozzolans, which is used as a material for construction and insulation.[2] It is marketed under names like Hempcrete, Canobiote, Canosmose, Isochanvre and IsoHemp.[3] Hempcrete is easier to work with than traditional lime mixes and acts as an insulator and moisture regulator. It lacks the brittleness of concrete and consequently does not need expansion joints.[3] The result is a lightweight insulating material ideal for most climates as it combines insulation and thermal mass.

* (TEXTILE) warp knitting / raschel

Raschel knits do not stretch significantly and are often bulky; consequently, they are often used as an unlined material for coats, jackets, straight skirts and dresses.  These fabrics can be made out of conventional or novelty yarns which allows for interesting textures and designs to be created.[5]  The qualities of these fabrics range from "dense and compact to open and lofty [and] can be either stable or stretchy, and single-faced or reversible.[5]  The largest outlet for the Raschel warp knitting machine is for lace fabric and trimmings. Raschel knitting is also used in outdoors and military fabrics for products such as backpacks. It is used to provide a ventilated mesh next to the user's body (covering padding) or mesh pockets and pouches to facilitate visibility of the contents (MIL-C-8061).

also for biotextiles
The warp knitting process is also being used to create biotextiles.  For example, a warp knitted polyester cardiac support device has been created to attempt to limit the growth of diseased hearts by being installed tightly around the diseased heart.  Current research on animals "have confirmed that … the implantation of the device reverses the disease state, which makes this an alternative innovative therapy for patients who have side effects from traditional drug remedies".[14]

Polycarbonates used in engineering are strong, tough materials, and some grades are optically transparent. They are easily worked, molded, and thermoformed.  Because of these properties, polycarbonates find many applications. Polycarbonates do not have a unique resin identification code (RIC) and are identified as "Other", 7 on the RIC list. Products made from polycarbonate can contain the precursor monomer bisphenol A (BPA). 
Polycarbonates received their name because they are polymers containing carbonate groups (−O−(C=O)−O−). A balance of useful features, including temperature resistance, impact resistance and optical properties, positions polycarbonates between commodity plastics and engineering plastics.

* Poly (methyl methacrylate) / PMMA / acrylic sheets / plexiglas / "plexi"

[...] belongs to a group of materials called engineering plastics. It is a transparent thermoplastic. PMMA is also known as acrylic, acrylic glass, perspex, or  plexiglass, as well as by the trade names and brands Crylux, Plexiglas, Acrylite, Astariglas, Lucite, Perclax, and Perspex, among several others (see below). This plastic is often used in sheet form as a lightweight or shatter-resistant alternative to glass. It can also be used as a casting resin, in inks and coatings, and for many other purposes. 
Although not a type of familiar silica-based glass, the substance, like many thermoplastics, is often technically classified as a type of glass, in that it is a non-crystalline vitreous substance—hence its occasional historic designation as acrylic glass. Chemically, it is the synthetic polymer of methyl methacrylate. It was developed in 1928 in several different laboratories by many chemists, such as William Chalmers, Otto Röhm, and Walter Bauer, and first brought to market in 1933 by German Röhm & Haas AG (as of January 2019, part of Evonik Industries) and its partner and former U.S. affiliate Rohm and Haas Company under the trademark Plexiglas.[5]
PMMA is an economical alternative to polycarbonate (PC) when tensile strength, flexural strength, transparency, polishability, and UV tolerance are more important than impact strength, chemical resistance, and heat resistance.[6] Additionally, PMMA does not contain the potentially harmful bisphenol-A subunits found in polycarbonate and is a far better choice for laser cutting.[7] It is often preferred because of its moderate properties, easy handling and processing, and low cost. Non-modified PMMA behaves in a brittle manner when under load, especially under an impact force, and is more prone to scratching than conventional inorganic glass, but modified PMMA is sometimes able to achieve high scratch and impact resistance.

* calcium carbide

Dutch use it for boom boom lol

In chemistry, a carbide usually describes a compound composed of carbon and a metal.  In metallurgy, carbiding or carburizing is the process for producing carbide coatings on a metal piece.[1]

Calcium Carbide reacts with WATER and MOISTURE to produce flammable Acetylene gas and Lime. The heat of the reaction may ignite the Acetylene. Calcium Carbide reacts with COPPER, SILVER, MERCURY and BRASS to form explosive compounds such as METAL ACETYLIDES.

Nb/Sn phase diagram
#toprint #tee

Niobium-tin and Niobium-titanium are essential alloys for the industrial use of superconductors, since they remain superconducting in high magnetic fields (30 T for Nb3Sn, 15 T for NbTi); there are 1200 tons of NbTi in the magnets of the Large Hadron Collider, whilst Nb3Sn is used in the windings of almost all hospital MRI machines. 


Hafnium or zirconium added to niobium–tin increases the maximum current density in a magnetic field. This may allow it to be used at 16 tesla for CERN’s planned Future Circular Collider.[17]

(Kevlar next-gen) Dyneema / Spectra / Aramid (→textile)
<vgupta here
Dyneema. Stronger, lighter, still pretty cut resistant.

While Kevlar fibers such as Aramid that has Hydrogen bonds with a very short molecular length compared to Dyneema.
Therefore, Kevlar has lower strength than the Dyneema. Both fibers materials have higher tensile strength per its weight as a ratio.

"Dyneema is a superlight fiber that's stronger than steel at the molecular level — and its use is becoming widespread in outdoor equipment"

Don't use gasless. 10 or 15 litre.
Ask the class to instruct you on vertical and horizontal lap welds and fillet welds. Master those and you'll be good for panel welding

Construction: Joist

"a length of timber or steel supporting part of the structure of a building, typically arranged in parallel series to support a floor or ceiling."

A joist is a horizontal structural member used in framing to span an open space, often between beams that subsequently transfer loads to vertical members. When incorporated into a floor framing system, joists serve to provide stiffness to the subfloor sheathing, allowing it to function as a horizontal diaphragm. Joists are often doubled or tripled, placed side by side, where conditions warrant, such as where wall partitions require support. 
Joists are either made of wood, engineered wood, or steel, each of which have unique characteristics. Typically, wood joists have the cross section of a plank with the longer faces positioned vertically. However, engineered wood joists may have a cross section resembling the Roman capital letter "I"; these joists are referred to as I-joists. Steel joists can take on various shapes, resembling the Roman capital letters "C", "I", "L" and "S".
