Carbon carbon composite material is carbon fiber reinforced carbon matrix composites, with high strength, high modulus, high dimensional stability, high conductivity, high fracture toughness, low density, heat expansion coefficient is small, thermal shock resistance, ablation resistance, chemical inertness and a series of advantages, as a new type of resistance material for high temperature structural and functional integration engineering development rapidly. At present, widely used in aerospace aircraft structural materials, solid motor nozzle, civil, military aircraft and racing friction brake materials, as well as biological engineering structural materials. At first because of the relatively high price of C / C composites limits its application in the field of industrial, in recent years, with the carbon fiber raw material and manufacturing cost…
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…
