Abstract
Special C-shaped carbon fibers, melt spun from mesophase pitch, were used as micro-molds to form nested dual fibers and ceramic fibers. By wetting these carbon fibers in a wet chemical precursor, and subsequently heat treating, ceramic fibers of various compositions were formed. Also, through proper control, carbon-ceramic nested fibers were produced. The ceramic materials were silica, alumina, silicon carbide, hydroxyapatite, and zirconia. The ceramic fibers could be formed with non-circular transverse cross-sectional perimeters.
