ABSTRACT:
A carbon fabric of high conductivity and high density is formed of oxidized fibers of polypropylene. The oxidized fibers have a carbon content at least 50 wt %, an oxygen content at least 4 wt %, and a limiting oxygen index at least 35%. The carbon fabric is made by preparing a raw fabric obtained from oxidized fibers of polypropylene by weaving and then carbonizing the raw fabric.
