ABSTRACT:
Microcellular carbon filaments having a specific gravity no greater than about 1.4 are formed from PAN foamed filaments by carbonizing. These low density carbon filaments, which may also be hollow, have improved insulation properties compared with conventional PAN precursor carbon fibers and can be used as a replacement to rayon precursor carbon fibers where greater insulation is necessary.
