Abstract
A C/C composite including a carbon matrix and carbon fibers and exhibiting a crystal structure of the carbon matrix differing between (a) the portion at and in the vicinity of the interface between the carbon fibers and the carbon matrix and (b) the other portion of the carbon matrix and excelling in strength and thermal conductivity is produced by a method which includes intercalating a carbonizing catalyst in carbon fibers, causing said carbon fibers having said carbonizing catalyst intercalated therein to be impregnated with a precursor of a carbon matrix, and then firing the product of impregnation.
