Carbon carbon composite material can be used in the national defense industry and aerospace industry. C/C composite material is made of PAN pre-oxidized fiber,use CVI and resin impregnation processing.it has a high specific strength,erosion resistance, thermal shock resistance,high temperature resistance,etc. After analogue simulation to the CVI processing of carbon carbon composite material and optimization of CVI processing,we could meet Computer automatic control of CVI processing and carbonization process,and reach the international advanced level. In the early days,the solid rocket motor nozzle is made of graphite material and high strength steel or aluminium alloy,the weight of them increased costs and reduce the working efficienfy of the engine.with the rapid development of composite materials,the carbon carbon composite material replace the graphite material.…
Carbon fiber cloth, also known as carbon fiber cloth, carbon fiber, carbon fiber woven cloth, carbon fiber pre dipped cloth, cloth reinforced by carbon fibre, carbon cloth, carbon fiber fabric, carbon fiber, carbon fiber sheet, prepreg. Carbon fiber cloth is a kind of unidirectional carbon fiber reinforced carbon fiber products, 12K is often used for weaving. [1] Can provide two kinds of thickness: 0.111mm (200g) and 0.167mm (300g). Variety of widths: 100mm, 150mm, 200mm, 300mm, 500mm, and other special width required for engineering. With the continuous development of carbon fiber cloth industry, more and more industries and enterprises to use carbon fiber cloth, but also a sector enterprises to enter the carbon fiber cloth industry and development. Carbon fiber cloth…
The carbon carbon composite material has a big difference to the superalloy and ceramic materials. Under inert conditions,even the temperature reach 20000C,the strength of the C/C material can still remain unchanged situation,the strength will not reduce. The carbon carbon composite material have a good resistance to thermal shocks and excellent mechanical properties. However, the fatal weakness of CFC material is the low oxidation resistance.although the C/C material has a high specific strength, high specific stiffness and high temperature stability,as one attractive structure material,when the temperature reach 4000C,the carbon carbon composite material start to oxidize. So the most researches on the C/C composite is how to avoid or reduce the degree of oxidation,and also many researches on the processing of the…
