Chemical fiber fabric carbon fiber fabric
The carbon fiber is a kind of high-strength, high-modulus fiber made of polypropylene rayon fiber, viscose fiber, or pitch fiber, which is prepared by heating out all other elements except carbon. It has good chemical stability and high temperature resistance and is an excellent structural material in high performance reinforced composites.
According to the carbonization temperature, carbon fibers can be divided into three types.
(1) Ordinary type (A type) carbon fiber: carbon fiber obtained by carbonization at 900 to 1200°C. This carbon fiber has a low strength and elastic modulus, generally less than 11 cN/dtex, and a modulus less than 1346 cN/dtex.
(2) High-strength (Type II or Type C) carbon fibers: carbon fibers obtained by carbonization at 1300 to 1700°C. This carbon fiber has a high strength of 14 to 17 cN/dtex and a modulus of 1384 to 1661 c/dtex.
(3) High-modulus (I- or B-type) carbon fibers, also known as graphite fibers: refers to carbon fibers obtained after carbonization and high temperature graphitization above 2500°C. This kind of carbon fiber has high strength, about 9.8~12.2cN/dtex, high modulus, generally up to 1711cN/dtex or even up to 3178cN/dtex.
