  2. Carbon fibers - Wikipedia

    en.wikipedia.org/wiki/Carbon_fibers

    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. [1] Carbon fibers have several advantages: high stiffness, high tensile strength, high strength to weight ratio, high chemical resistance, high ...

  4. Carbotanium - Wikipedia

    en.wikipedia.org/wiki/Carbotanium

    This is because carbon fiber has the highest strength-to-density ratio of any current fiber and titanium has the highest strength-to-density ratio of any current metal. As a result, carbotanium can withstand temperatures up to 315 °C. [2] The material properties of carbotanium are a mixture of those of a titanium alloy and a carbon fiber.

  5. Carbon-fiber reinforced polymer - Wikipedia

    en.wikipedia.org/wiki/Carbon-fiber_reinforced...

    The properties of a CFRP depend on the layouts of the carbon fiber and the proportion of the carbon fibers relative to the polymer. [6] The two different equations governing the net elastic modulus of composite materials using the properties of the carbon fibers and the polymer matrix can also be applied to carbon fiber reinforced plastics. [ 7 ]

  6. Composite laminate - Wikipedia

    en.wikipedia.org/wiki/Composite_laminate

    A small sample of aerospace grade carbon-fibre/epoxy laminate. In materials science, a composite laminate is an assembly of layers of fibrous composite materials which can be joined to provide required engineering properties, including in-plane stiffness, bending stiffness, strength, and coefficient of thermal expansion.

  7. Pitch-based carbon fiber - Wikipedia

    en.wikipedia.org/wiki/Pitch-based_carbon_fiber

    Orienting and aligning these crystalline regions gives further strength to the fibers, specifically if the orientation is along the fiber axis. Carbonization and graphitization are the two processes responsible for this alignment of the crystalline regions. Pitch based carbon fiber is lower in strength than fiberglass; however, it has a very ...

  8. Metal matrix composite - Wikipedia

    en.wikipedia.org/wiki/Metal_matrix_composite

    MMCs are fabricated at elevated temperatures, which is an essential condition for diffusion bonding of the fiber/matrix interface. Later on, when they are cooled down to the ambient temperature, residual stresses (RS) are generated in the composite due to the mismatch between the coefficients of the metal matrix and fiber. The manufacturing RS ...

  9. Carbon - Wikipedia

    en.wikipedia.org/wiki/Carbon

    Carbon (from Latin carbo 'coal') is a chemical element; it has symbol C and atomic number 6. It is nonmetallic and tetravalent—meaning that its atoms are able to form up to four covalent bonds due to its valence shell exhibiting 4 electrons. It belongs to group 14 of the periodic table. [13] Carbon makes up about 0.025 percent of Earth's ...
