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 comprises a matrix and 20 volume% or more of carbon fibers, and is characterized in that: the matrix contains ceramic powder that includes boron carbide powder having an average particle diameter of 5 µm or less; and an amount of the ceramic powder is 32 volume% or more based on volume of the carbon fibers.
