Process for the production of carbon fibers |
摘要 |
A process for the production of carbon fibers, including melt-spinning mesophase pitch having an optically anisotropic content of at least 90%, a softening point of 190° C. to 280° C. and a heating weight loss of 0.7% by weight or less at a spinning temperature to form a spun fiber, infusibilizing the spun fiber to obtain an infusible fiber and carbonizing the infusible fiber.
