Abstract

Pitch-based carbon fibers on which silicone type spin finish oils are remained in the amount of 0.1 - 2.0% by weight of said fibers and having a stack height of graphitic layers Lc (002) of 16 - 28Å, a graphitic interlayer spacing distance d002 of 3.46 - 3.49Å, a tensile strength of 5 - 50 Kgf/mm² and an elongation of 0.3 - 8.0% are provided. They show good cohesiveness and lubricity of bundles and superior in adaptation to various kinds of processes.
