Abstract

PURPOSE:To obtain a high-strength and high-modulus carbon fiber free from fissure on the surface, by melt spinning high-softening pitch followed by being made infusible and carbonization or graphitization, using a spinneret in which the insert has been extended beyond the contracted flow section of the nozzle. CONSTITUTION:Using a spinneret in which the insert 4 has been put from the inlet hole 1 side of a spinning nozzle beyond the contracted flow section 2, high-softening pitch is brought to melt spinning followed by being made infusible and carbonization or graphitization, thus obtaining the objective carbon fiber with the orientation texture of carbon molecule representing random structure or onion skin structure on the fiber section.
