ABSTRACT:
A method for producing high strength, high modulus carbon fibers having a modulus of elasticity of 75 tonf/mm.sup.2 or more and a tensile strength of 250 kgf/mm.sup.2 or more is provided. This method comprises graphitizing mesophase-pitch-based carbon fibers at a temperature of 2600.degree. C. or more for several seconds or for several minutes while stretching said fibers with a stretching ratio which satisifies specified relations.
