PURPOSE:To obtain a composite material exhibiting excellent strength and fracture toughness at a normal temp. to a high temp. by using a silicon carbide based inorganic fiber as a reinforcing material and a specific carbide based nanocomposite material or nitride based nanocomposite material as a matrix. CONSTITUTION:The silicon carbide based inorganic fiber reinforced ceramic composite material is obtained by using the silicon carbide based inorganic fiber as the reinforcing material and the carbide based or nitride based nanocomposite material nanocomposited by carbide particles and/or nitride particles as the matrix. In the nanocomposite material, the nitride of an element such as silicon, boron, aluminum, magnesium and the composite nitride of these elements, sialon, etc., are mentioned as the nitride based ceramic to be a base phase and dispersion particles. Also, in the nanocomposite material, the carbide of an element such as silicon, titanium, zirconium, aluminum, uranium, tungsten, tantalum and a composite carbide of these elements are exemplified as the carbide based ceramic to be a base phase and dispersion particles. |
