Advanced composite materials are mainly resin based, metal based, Tao Ciji and carbon matrix composites, such as four categories, metal matrix composites have been used to push the compressor and fan blades of more than 10 of the engine, but the key components of high temperature can only be used in ceramic matrix composites and carbon fiber reinforced carbon matrix composites. The former work temperature can be as high as 1650 degrees Celsius, while the carbon carbon composite material is more than 1650 degrees Celsius, especially more than 2000 degrees Celsius, the only candidate materials. The application scope of carbon carbon composites has been expanding, as the anti ablation materials and high speed braking friction materials have been successfully applied…
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…
