ABSTRACT:
Hollow carbon and graphite filaments having a specific gravity of about 20-50% less than conventional solid carbon fibers made of the same precursor resin are formed by spinning hollow precursor resin filaments. These low density hollow carbon filaments have improved insulating properties compared with conventional solid carbon fibers and have an excellent bending strength to weight ratio.
