Claims (2)

섬유의 횡단면에 있어서, 섬유의 외표층보다 섬유의 내부에 있어서 결정성이 실질적으로 높은 것을 특징으로 하는 피치계 탄소섬유의 제법.In the cross section of a fiber, the manufacturing method of the pitch type carbon fiber characterized by the fact that crystallinity is substantially higher inside the fiber than the outer surface layer of the fiber. 광학적이방성 부분을 주성분으로 하는 탄소질 피치를 방사하고, 얻어진 탄소질피치섬유를 섬유의 횡단면내의 외표층부만을 선택적으로 불융화하고, 그런후 그의 외표층부만 불융화한 섬유를 소성하는 것을 특징으로 하는 피치계 탄소섬유의 제법.A carbonaceous pitch having the optically anisotropic portion as a main component is radiated, and the obtained carbonaceous pitch fiber is selectively infusified only in the outer layer portion in the cross section of the fiber, and then the fiber in which only the outer layer portion is infusified is fired. Production method of pitch carbon fiber. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
