Using polyacrylonitrile-based, viscose-based or pitch-based fibers, high-temperature oxidative carbonization is used to prepare high-strength and high-modulus carbon fibers with a carbon content of more than 90%. This will be used as a reinforcing material, and an advanced composite material compounded with resin, metal, ceramics and carbon. This material is an excellent material for manufacturing high-tech equipment such as aerospace and aviation.
The carbon fiber is graphitized at a high temperature to achieve a carbon content of more than 95%, and a graphitized carbon fiber with a higher modulus can be obtained.
Using polycarbosilane as raw material, silicon carbide ceramic fiber can be obtained by high temperature oxidation and carbonization. Its heat resistance and oxidation resistance are better than carbon fiber, and the use temperature of the fiber reaches 1200°C.
