Introduction


A Carbon Fiber is a fibrous carbon material having a micrographite crystal structure made by fibrillation of Acrylic base goods, a knowntextile material, or from oil/coal arena following by treating with a certainheat treatment.


Carbon fibers, is the latest industrialized fibre undercommercial production, mainly classified into PAN-based, pitch-based andrayon-based production process. Among them, PAN-based carbon fiber is in thelargest production and best used in volume. In the early 1970s, commercialproduction of PAN-based and isotropic pitch-based carbon fibers was started in Japan. In the latter half of 1980s, anisotropic pitch-based carbon fiber manufacturersbroke into the market. Japanese firm taking an innovative advantage of tirelesstechnological improvement and business expansion, been keeping their positionas largest producer of carbon fibre in terms of quality and quantity across theglobe.


Utilization of carbon fibre by itself is not the convention.Generally, customers apply carbon fibers for various purposes likereinforcement and functionality of composite materials, made from resin,ceramic or metal as intercellular substance. Carbon fibers are extensivelyemployed to a gravid mixture of applications with extreme mechanicalcharacteristics (specific tensile enduringness, particular modulus) and otherfeatures due to carbon substance (eg. low density, low coefficient of thermoenlargement, resistance to heat, chemical resistance, self-lubricity, etc.).
