| Abstract: | A spinnable pitch for general carbon fiber was prepared with coal hydrogenation pyrolysis asphalt after air oxidation and N2 blowing with a high yeild of more than 70 %. The spinnable pitch was then used to prepare general pitch carbon fiber after spinning, preoxidation, and carbonization. The result showed that general pitch carbon fiber possessed good capabilities with a diameter of 12.2 um, a tensile strength of 623 MPa, a stretch modulus of 30.5GPa, and a tensile stretch 2.05%. |
