Abstract

Carbon composites were prepared with pitch-based round, C, hollow-type carbon fibers and pitch matrix. The thermal conductivities parallel and perpendicular to the fiber axis were measured by steady-state method. It was found that the thermal conductivities depended on the cross-sectional forms of the reinforcing fibers as well as the reinforcing orientation and carbon fiber precusors. Especially, mesophase pitch-based hollow carbon fiber-carbon composites had the most excellent thermal anisotropy, which was above 100.

Keywords
