High strength high modulus carbon fibers

摘要

High strength, high modulus carbon fibers derived from high mesophase content pitch, having a plurality of sheets formed of planes of hexagonal carbon networks oriented, in the direction of the fiber axis and having a cross-sectional arrangement which does not carbonize to a graphitic structure are characterized by electron and X-ray diffraction pattern wherein the (10) band is not resolved into (100) and (101) lines, by an interlayer spacing greater than 3.38 angstrom and by negative magnetic resistivity when composed to graphitized fibers.
