Inorganic fibers made of carbon. The carbon content of the fibers is greater than 90%. Generally divided into three categories: ordinary, high-strength and high-model. Compared with glass fiber (GF), the Young's modulus is more than 3 times; compared with Kevlar fiber (KF-49), not only the Young's modulus is about 2 times, but also in organic solvent, acid , It does not swell or swell in alkali, and its corrosion resistance is outstanding.
Carbon fiber is a fibrous carbon material. It is stronger than steel, less dense than aluminum, more resistant to corrosion than stainless steel, more resistant to high temperature than heat-resistant steel, can conduct electricity like copper, and has electrical, thermal and mechanical properties.
