Abstract
The present invention provides a carbon-carbon composite material consisting of a matrix carbon and a fibrous reinforcing carbon, said matrix carbon consisting substantially of optically anisotropic carbon and said fibrous reinforcing carbon consisting substantially of optically isotropic carbon, and said matrix carbon and fibrous reinforcing carbon forming an interface without an intervening third material, wherein said composite material has a fracture surface showing a uniform vitreous light reflection, and a method for the preparation thereof. The composite material has a high flexural strength and a very low gas permeability and is useful as a molding material in the fields of high temperature chemistry, the atomic energy industry and medicine.
