Carbon fiber reinforced C-SiC composites have a series of excellent properties, such as high temperature resistance, high specific strength, high specific modulus, low thermal expansion coefficient, excellent high temperature thermodynamic stability and so on. It also has the characteristics of high density, heat shock resistance, ablation resistance and thermal chemical stability. It is a new type of composite material with high temperature resistance and high temperature, and is also a new type of high temperature resistant material, such as aerospace, advanced energy system, high temperature heat exchange system, etc. In the existing preparation process, molten silicon infiltration reaction method (liquid silicon infiltration, LSI) due to the short preparation period, low cost, can realize net shape forming advantages, has great potential…
Thermal conductivity of graphite, also known as the graphite radiating fins, a new thermal cooling material, has the unique grain orientation and along the two directions of the uniform heat conduction, the lamellar structure can well adapt to any surface, the heat shield assembly and improve consumer electronic products performance. The unique combination of thermal conductivity and thermal conductivity of graphite thermal conductivity is a good choice for the thermal management solution. Ultra high thermal conductivity in the plane of thermal conductive graphite sheets with W/m-K 150-1500. The chemical composition of the thermal conductivity of graphite materials (thermal flexible graphite sheet is mainly single carbon (c) elements, is a kind of natural elements in minerals. Polymer film can be graphite…
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…
