COMPOSITE MATERIAL FOR HIGH TEMPERATURE USE

摘要

PURPOSE:To obtain a high-temperature-use composite material advantageously applicable to a high-temperature-use material e.g. especially for a jet engine and a gas turbine of a plane returning from the space, etc. CONSTITUTION:This high-temperature-use composite material comprises an inorganic fiber-reinforced complex oxide 2 of silicon dioxide and an oxide of a rare earth element, wherein the silicon dioxide is contained in a concentration of 5-67% in the complex oxide. The inorganic fiber consists of silicon carbide fiber or carbon fiber 1 coated mainly with silicon carbide.
