Abstract: The composite includes inorganic fiber for reinforcement and a matrix of 40 to 95% by weight of silicon carbide ceramic and 5 to 60% by weight of an oxide phase dispersed in the silicon carbide ceramic. The oxide phase forms a continuous network structure in the matrix and includes ZrSiO4, BaO—MgO—Al2O3—SiO2 glass ceramic or Sro—Al2O3—SiO2 glass ceramic. The matrix surrounds and fills voids between the inorganic fiber.

Abstract: A reinforcement for composite materials is disclosed, which comprises a number of filaments of inorganic long fiber and glass and/or glass ceramic present in the gaps among the filaments and having a wire or tape form. Also disclosed is a metallic or ceramic composite material composed of a plurality of the reinforcements and a metal or intermetallic compound or ceramic which is present in the gaps among the individual reinforcements.

Abstract: A fastening member is formed from a fiber-reinforced ceramic composite material, in which a ceramic material is reinforced with a plurality of inorganic long fibers. The inorganic long fibers are located in the ceramic material such that first orientated layers, in which the inorganic long fibers are orientated in a predetermined direction, and second orientated layers, in which the inorganic long fibers are orientated in a direction different from the direction of orientation of the inorganic long fibers in the first orientated layers, may be laminated alternately.
