Summary on Carbon Fibres

1. SUMMARY
1.1 Identity, physical and chemical properties
Carbon/graphite fibres are filamentary forms of carbon produced by high-temperature processing of one of three precursor materials: rayon (regenerated cellulose), pitch (coal tar or petroleum residue) or polyacrylonitrile (PAN). Nominal diameters of carbon fibres range between 5 and 15 µm. Carbon fibres are flexible and electrically and thermally conductive, and in high performance varieties have high Young's modulus (cooefficient of elasticity measuring the softness or stiffness of the material) and tensile s…
