ABSTRACT:
Chopped carbon yarn is produced by spinning continuous pitch yarn, treating the pitch yarn with an oxidizing composition, chopping the pitch yarn into short lengths, collecting the chopped pitch yarn into a bulk form, and subjecting the chopped pitch yarn to a heat treatment in a substantially non-reactive atmosphere to produce chopped carbon yarn.
