ABSTRACT:
The present invention provides an improvement in the process of producing pitch-based carbon fibers comprising the steps of spinning a spinnable pitch, treating the resulting pitch fibers for rendering infusible, and carbonizing the same, the improvement comprises the step of removing the surface layer from the carbon fibers obtained in said process.
