The preparation of PAN-based carbon fiber
Polyacrylonitrile carbon fiber-polyacrylonitrile fiber as raw material is made of carbon fiber, mainly used for composite reinforcements. Homopolymer or copolymer of polyacrylonitrile fiber reinforced carbon fiber can be produced. In order to manufacture high performance carbon fibers and increases productivity, copolymer of polyacrylonitrile fiber as raw material is often used in industry. The raw material itself is: impurities, defects, less uniform size, and the finer the better; high strength, filament less chain molecules in the fibers orientation along the fiber axis, the higher the better, usually greater than 80%; conversion performance.
