Abstract
A carbon composite material reinforced with a carbon fiber and an inorganic fiber. The composite material has a core formed of a carbon fiber-reinforced carbon composite comprising a carbon fiber reinforcement and a carbon matrix, The core is externally covered with an inorganic fiber-reinforced carbon composite comprising an inorganic fiber reinforcement, other than carbon, and a matrix composed either of carbon alone or a mixture of carbon and boride. This provides for sound and steady protection against oxidation, as well as for retention of high strength in an oxidizing atmosphere at high temperatures.
