ABSTRACT:
Extremely high modulus carbon fibers can be produced by carbonization at a substantially lower temperature, for example, at about 2500.degree. C. This is made possible by selectively stabilizing only an outer surface layer portion of a carbonaceous pitch-based fiber comprised mainly of optically anisotropic components, while retaining the inner portion of the fiber in a non-stabilized state and without damage to the crystallinity thereof.
