Carbon carbon composites (CFC) is a kind of material formed by high strength carbon fiber and carbon matrix which has been processed by enhancement graphitization,it can be widely used in various structure, heater and vessel under the high temperature environment . Carbon carbon composites (CFC) has the following advantages compared with the traditional engineering materials of : 1).High strength (5 times steel). 2).High temperature resistance (it can still maintain excellent mechanical and electrical properties under 2000℃). 3).Thermal shock resistance. 4).The low coefficient of thermal expansion. 5).The small thermal capacity. 6).The low density (1.7). 7).The excellent corrosion resistance and radiation performance. The main application fields of carbon carbon composites are: 1).The field of aerospace. Carbon carbon composites (CFC) can be used…
Carbon carbon composites is one kind of high performance friction material, which has been successfully applied in the aviation industry. Compared with other friction materials, carbon carbon composite materials with low density, high temperature resistant, high strength, thermal shock resistance, corrosion resistance, good vibration resistance and suitable friction coefficient and friction performance, is a comprehensive performance ,excellent high temperature friction material. Carbon carbon composites have become the preferred material for aircraft brake discs. In addition to do the brake disc, carbon carbon composite material can also be used as sliding bearing material and piston of internal combustion engine. As the friction material, carbon carbon composites will be more widely used. Therefore, it is of great significance to study the tribological…
Carbon fiber reinforced polymer composites are widely used in foreign liquid rocket engines. Such as Germany's Astrium design, made with nozzle extension a water cooled thrust chamber test, as well as the Ariane rocket engine design for 5 level fire made the scale of thrust chamber extension nozzle; the 5 Ariane rocket upper stage engine engine and engine spray pipe Aestus HM-7 extension; engine nozzle extension; a an upper stage engine Snecma Venus motive nozzle extension development of French RS-72 company; USA Inc research expansion cycle liquid rocket upper stage engine RL10B-2 motivation extension nozzle Pratt & Whitney; the French company developed the Snecma expansion cycle LH2 / lox engine can be extended Vinci upper stage engine nozzle; USA Inc…
