Carbon fiber - Wikipedia, the free encyclopedia Carbon fiber is most notably used to reinforce composite materials, particularly the class of materials known as graphite reinforced plastic. Reinforced carbon-carbon (RCC) consists of carbon fibre-reinforced graphite, and is used structurally in high-temperature applications, such as the nose cone and leading edges of the space shuttle. Each carbon filament is made out of long, thin sheets of carbon similar to graphite. en.wikipedia.org /wiki/Carbon_fibre   (615 words)

Glass-reinforced plastic - Wikipedia, the free encyclopedia Like graphite-reinforced plastic, the composite material is commonly referred to by the name of its reinforcing fibers (fiberglass), an example of part-for-whole metonymy. Glass-reinforced plastic (GRP), is a composite material or fibre reinforced plastic made of a plastic reinforced by fine fibers made of glass. The plastic is most often polyester or vinylester, but other plastics, like epoxy (GRE), are also sometimes used. en.wikipedia.org /wiki/Glass-reinforced_plastic   (317 words)

WAC 296-17-59202: Classification 3510. Graphite composites are also known as carbon reinforced composites. Plastic powder, mixed with color, is poured into molds; molds are closed and moved on a rotating arm through a large oven in a tumbling action while the mold heats. Sheets of plastic film are usually made by extruding a tube of hot plastic, expanding it with air pressure, then passing it through a series of rollers and cutters which roll it flat and cut it into two separate sheets. apps.leg.wa.gov /wac/default.aspx?cite=296-17-59202   (1742 words)

Articles - Reinforced concrete The premium fibers are graphite reinforced plastic fibers, which are nearly as strong as steel, lighter-weight and corrosion-proof. Reinforced concrete (ferro concrete) is concrete in which reinforcement bars ("rebars") or fibers have been incorporated to strengthen the naturally brittle concrete. In wet and freezing climates, reinforced concrete for roads, bridges, parking structures and other structures that may be exposed to deicing salt may require epoxy-coated rebar or a well composited concrete well planes structure. www.mafox.com /articles/Ferroconcrete   (1296 words)

Fiber reinforced plastic sheet molding compound - Patent 4339490 Therefore, the fiber-reinforced plastic molded articles prepared by using the sheet molding compound of the present invention contain the reinforcing fibers at a uniform density to exhibit uniform strength, and exhibit very good appearance without permitting the reinforcing fiber to protrude on the surfaces of the molded articles. The unhardened reinforced plastic material was supplied into a metal mold for preparing a spool, and was molded under the pressure of 70 kg/cm.sup.2 at 130.degree. Representative examples of the reinforcing fiber used for preparing the sheet (I) include organic fibers such as polyester fibers, polyamide fibers, aromatic polyamide fibers and polyamideimide fibers, and inorganic fibers such as glass fibers, silicon carbide fibers, alumina fibers, titanium fibers, steel fibers, carbon fibers and graphite fibers. www.freepatentsonline.com /4339490.html   (3465 words)

Gearing up with plastic However, lower-modulus plastic gear teeth deform to compensate for the inaccuracies, and their softer material absorbs impacts, often making plastic gears quieter than more costly metal gears that are one or two AGMA classes higher in quality. Plastics are naturally more prone to dimensional creep than metal, and creep in plastic gears depends on duty cycle and temperature. Plastic gears impose no special restrictions on gear ratios, and the required accuracy can be achieved with today's molding machines and materials. www.memagazine.org /backissues/september98/features/gearup/gearup.html   (3166 words)

Chapter 5 - High-Performance Concretes Reinforced concrete itself is a composite material, where the reinforcement acts as the strengthening fiber and the concrete as the matrix. Greater shear strength increases were found with fiber reinforced high strength concrete specimens (60% with steel and 17% with polypropylene fibers) than with fibers reinforced normal strength concrete specimens (36% with steel fibers and no increase with polypropylene fibers) when compared to the strengths of their respective unreinforced plain concrete specimens. Plastic ducts housing the cables were grouted with high-strength epoxy and mortar for bonding purposes, and the temporary anchorages were removed. www.tfhrc.gov /structur/hpc/hpc2/chap5.htm   (19679 words)

mechlab31.doc Three types of graphite reinforced epoxy composite were tested: one with fibers parallel to the long direction, one with fibers perpendicular to the long direction, and one with fibers at a 45° angle to the long direction. Aluminum and graphite fiber reinforced epoxy were tested to determine whether they were isotropic or anisotropic. The 0° and 90° samples were only reinforced in one direction, so one direction was susceptible to a comparably high strain due to the lack of reinforcement. filebox.vt.edu /s/shix/mechlab31.doc   (1168 words)

Nat' Academies Press, Undersea Vehicles and National Needs (1996) The Navy's AUSS uses graphite reinforced plastic/epoxy for its main pressure vessel, but the future of such materials in pressure vessel applications remains unclear, primarily because of difficulties in manufacturing processes and high cost (Stachiw and Frame, 1988; Stachiw, 1993). Currently, nonmetallic materials, including filamentwound epoxies, Kevlar, and graphite composites and ceramics, are used for military applications in both primary structures (pressure hulls) and secondary structures (fairings). Advanced materials for fairings include graphite epoxy layup or fiberglass constructions using a fiber-impregnated, high-density polyethylene that is also acoustically transparent (Sloan and Nguyen, 1992). books.nap.edu /books/0309053846/html/30.html   (1037 words)

WAC 296-17-704: Classification 6309. This term may be misleading in that a custom bicycle may be nothing more than the assembly of various components to produce the desired bicycle, or it could be the actual cutting, bending, and welding of tube metal, or the cutting, rolling and heating of graphite reinforced plastic material. Frame manufacturing operations in other classifications consist of extruding metal or plastic through dies to produce the desired frame material, or planing and molding the dimensional lumber to the desired appearance, cutting material in mass quantities, fastening frames together (mass production oriented) and boxing for shipment. Custom frame manufacturing covered by this classification is distinguishable from other frame manufacturing covered in classifications 3404, 2909, and 3512 in that custom frame making contemplated in classification 6309-20 consists of cutting frame material purchased from others with a specialized saw and fastening the pieces together with a small air nailer or finish screws. apps.leg.wa.gov /wac/default.aspx?cite=296-17-704   (3715 words)
