Document Type and Number:
WIPO Patent Application WO/2010/024462
Kind Code:
A1
Abstract:
Provided are pitch-derived graphitized short fibers which have high heat dissipation properties. The pitch-derived graphitized short fibers are characterized in that mesophase pitch was used as a raw material, and that the proportion of short fibers having a radius of curvature in the range of 10-60 cm is 60-99% of all fibers and the proportion of short fibers which, when examined with a scanning electron microscope, have a cleavage in the surface thereof is 30-99% of all fibers.
