Brief introduction and development of carbon carbon composites

Carbon carbon composite material(C/C) is highly valued by advanced technology research personnel,and till now,the carbon carbon composite material is still the main material of the strategic missile and solid rocket motor nozzle

  The carbon carbon composite material is carbon fiber reinforced matrix,is make the carbon fiber as the reinforced material,and make the carbon as the matrix,and use the processing and carbonization process to meet all carbon composite material. The carbon content of the carbon carbon composite material can be above 99% after high thermal processing. And it has many good properties.

  The density of carbon composite material is very low(<2.0 /cm3),it’s the 1/4 of Ni,1/2 of ceamic,it’s very important to some structure which has a light requirement. The high thermal performance of carbon carbon material is good,the strength of it can be stable under the 2200 centigrade,and even higher than this. This performance is good that other material can not meet.

  The alation performance of carbon carbon composite material is the main property, and it’s the main reason of it to be used in the aerospace industry. If it’s in the situation of period of time ,the tempterature can meet 3000 centigrade.

  The friction resistance of carbon carbon composite material is also good,the friction coefficient is low,and the property is stable,it’s the best material to be used for friction.

  It also has some other property,such as high specific strength, specific stiffness and high specific modulus etc.

  The development of the carbon carbon composite material experienced four stages,1, the basic research stage of carbon fiber and dense process,1961~1964,Japan and English produce the carbon fiber with PAN,reduce the cost of carbon fiber.2, C/C composite material has been a greatly developed during seventies,the multi direction knitting technology and high pressure liquid phase impregnation and CVI was published. And use these methods to make the high density C/C composite material. 3, the carbon carbon composite material was used in the space shuttle during eighties to be antioxidant. 4,and now, most researches are on how to reduce the cost and new technology.
