ABSTRACT:
Pitch based carbon fibers characterized in that their thermal conductivity is at least 1,000 W/m.multidot.K as measured at room temperature, their electrical resistivity is at most 1.2 .mu..OMEGA.m, their tensile modulus is at least 95 ton/mm.sup.2, their compression strength is at least 30 kg/mm.sup.2, and the ratio of crack-free fibers to cracked fibers is from 5/95 to 30/70, where the crack-free fibers are fibers having no cracks in their cross section, and the cracked fibers are fibers having cracks in their cross section.
