Abstract
Microcellular carbon filaments having a specific gravity about 20-30% less than conventional carbon fibers made of the same precursor resin are formed by foaming the precursor resin during spinning. These low density microcellular carbon filaments, which may also be hollow, have improved insulation properties compared with conventional carbon fibers, they have a higher than expected strength to weight ratio and adhere in a superior fashion to a variety of matrix materials.
