  2. Polyacrylonitrile - Wikipedia

    en.wikipedia.org/wiki/Polyacrylonitrile

    PAN fibers are the chemical precursor of very high-quality carbon fiber. PAN is first thermally oxidized in air at 230 °C to form an oxidized PAN fiber and then carbonized above 1000 °C in inert atmosphere to make carbon fibers found in a variety of both high-tech and common daily applications such as civil and military aircraft primary and ...

  3. 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 ...

    en.wikipedia.org/wiki/Pitch-based_carbon_fiber

    3) Carbonization is the process removing all non organic elements. In the case of carbon fibers, all elements except for carbon are removed. This is achieved by heating the fibers to high temperatures in an environment without oxygen. [6] [9] This step removes all impurities from the fibers and leaves crystalline carbon structures. These ...

    These thermal greases have low electrical conductivity and their volume resistivities are 1.5⋅10 15, 1.8⋅10 11, and 9.9⋅10 9 Ω⋅cm for 860, 8616 and 8617 respectively. The thermal grease 860 is a silicone oil with a Zinc Oxide filler and 8616 and 8617 are synthetic oils with various fillers including Aluminum Oxide and Boron Nitride.

  6. Carbon-fiber reinforced polymer - Wikipedia

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

    Carbon fibers are used for fabrication of carbon-fiber microelectrodes. In this application typically a single carbon fiber with diameter of 5–7 μm is sealed in a glass capillary. [ 36 ] At the tip the capillary is either sealed with epoxy and polished to make carbon-fiber disk microelectrode or the fiber is cut to a length of 75–150 μm ...

  7. Aerogel - Wikipedia

    en.wikipedia.org/wiki/Aerogel

    They are often manufactured as composite paper: non-woven paper made of carbon fibers, impregnated with resorcinol–formaldehyde aerogel, and pyrolyzed. Depending on the density, carbon aerogels may be electrically conductive, making composite aerogel paper useful for electrodes in capacitors or deionization electrodes.

  8. 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 ...

    en.wikipedia.org/wiki/Ceramic_matrix_composite

    The thermal protection system for the underside of the vehicle, comprising the nose, leading edges and lower surface of the wing, were designed and made by Herakles [32] using a ceramic matrix composite (CMC), carbon/silicon-carbide (C/SiC), in this case based on the liquid silicon infilration (LSI) process (see manufacturing procedures above ...
