Carbon carbon composite material is made of carbon fiber reinforced and carbon matrix. The carbon fiber is made from PAN,pitch, rayon etc. and after pre oxidation and carbonization process. The carbon content of carbon fiber is above 90%,and it has a high strength, high modulus and high temperature resistance. PAN base carbon fiber has a good property of strength,and it can be widely used for many industrial field,the PAN carbon fiber is 90% of the world's carbon fiber total. Now,the total output of carbon around the world is amost forty thousand tons. And the production yield of Japan Toray ,Tenax and Mitsubishi will reach 75% of all. The carbon fiber can be used in many field,such as bycicle structure,racing boat,…
The carbon carbon composite material is made of carbon matrix and reinforced carbon fiber,the whole system is consist of carbon element,the extremely strong attractive force make the material very stable. Under very high tempterature,it still can maintain solid,especially under the 2500 centigrade. And the mechanical strength will increase with the growing of the tempterature,and the chemical composition does not change. The carbon carbon composite material is the best high temperature resistant material. The 3D and 4D structure of the C/C material has been successfully used for the nose cone and nozzle. Strategic missile and anti missile reentry nose cone are made from the C/C composite material,and the structure is 3D material. Because of the accuracy requirements,the missile need the material…
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…
