  2. Ceramic matrix composite - Wikipedia

    en.wikipedia.org/wiki/Ceramic_matrix_composite

    Carbon. The most significant corrosion of carbon occurs in the presence of oxygen above about 500 °C (932 °F). It burns to form carbon dioxide and/or carbon monoxide. It also oxidizes in strong oxidizing agents like concentrated nitric acid. In molten metals, it dissolves and forms metal carbides. Carbon fibers do not differ from carbon in ...

  3. Kevlar - Wikipedia

    en.wikipedia.org/wiki/Kevlar

    Kevlar (para-aramid) [2] is a strong, heat-resistant synthetic fiber, related to other aramids such as Nomex and Technora.Developed by Stephanie Kwolek at DuPont in 1965, [3] [2] [4] the high-strength material was first used commercially in the early 1970s as a replacement for steel in racing tires.

  4. Metal matrix composite - Wikipedia

    en.wikipedia.org/wiki/Metal_matrix_composite

    For example, carbon fibers are commonly used in aluminium matrix to synthesize composites showing low density and high strength. However, carbon reacts with aluminium to generate a brittle and water-soluble compound Al 4 C 3 on the surface of the fiber. To prevent this reaction, the carbon fibers are coated with nickel or titanium boride.

  5. Non-ferrous metal - Wikipedia

    en.wikipedia.org/wiki/Non-ferrous_metal

    In metallurgy, non-ferrous metals are metals or alloys that do not contain iron (allotropes of iron, ferrite, and so on) in appreciable amounts.. Generally more costly than ferrous metals, non-ferrous metals are used because of desirable properties such as low weight (e.g. aluminium), higher conductivity (e.g. copper), [1] non-magnetic properties or resistance to corrosion (e.g. zinc). [2]

  6. GLARE - Wikipedia

    en.wikipedia.org/wiki/GLARE

    In a Glare3 grade, each glass fiber layer has two plies: one oriented at zero degrees, and the other oriented at ninety degrees. Glare (derived from GLAss REinforced laminate [1]) is a fiber metal laminate (FML) composed of several very thin layers of metal (usually aluminum) interspersed with layers of S-2 glass-fiber pre-preg, bonded together ...
