OXIDATION RESISTANT CARBON FIBER REINFORCED CARBON COMPOSITE MATERIAL AND PROCESS FOR PRODUCING THE SAME

摘要

An oxidation resistant carbon fiber reinforced carbon composite material comprising a matrix and 20 vol.% or more of a carbon fiber, characterized in that the matrix comprises powdery ceramics containing at least a powdery boron carbide of 5μm or less average particle diameter, the powdery ceramics contained in an amount of 32 vol.% or more based on the volume of carbon fiber.
