The present invention provides a new high-performance composite material that uses inexpensive materials, has high toughness, has a low coefficient of friction, excellent wear resistance, lower electrical resistance, and excellent electromagnetic wave absorption, and corresponding manufacturing method. A sintered body containing 0.1˜90 mass % of carbon nanotubes 2 and 99.9˜10 mass % of alumina-silica ceramic 3. The alumina-silica ceramic 3 contains 99.5˜5 mass % alumina and 0.5˜95 mass % silica. A nanocomposite 1, wherein the nano crystals of the carbon nanotubes 2 and the alumina-silica ceramic 3 are mutually intertwined, exists as a construction element. The carbon nanotubes 2 and alumina-silica ceramic 3 raw materials are placed in a water or alcohol solvent to form a slurry that is then stirred for 3˜180 minutes after which the solvent is removed from this mixture material that is then sintered in a non-oxygenated atmosphere in the temperature range of 800° C.˜1,800° C. for 5 minutes to 5 hours.
A high-performance composite material, comprised of sintered bodies containing 0.1˜90 mass % carbon nanotubes and 99.9˜10 mass % alumina-silica ceramic, wherein the alumina-silica ceramic contains 99.5˜5 mass % alumina and 0.5˜95 mass % silica;
A method of manufacturing the high-performance composite material comprising the steps of:
