Carbon carbon composite material used in the airplane is an advanced technology,and it’s already widely used in the aerospace field. The big difference between carbon Carbon brake disc and the other material is the material is used of carbon carbon composite material,it’s the heat reservoir,structure material and friction parts. The advantage of carbon carbon composite material mainly includes: the light weight,high strength under the high thermal situation,and no distortion,good friction property and long service time,the density of C/C composite is 1/4 of the steel,it can make the Boeing-747-400 lose weight about 800kg. The carbon carbon composite material will not change on the surface and the structure under the 2000 centigrade,during the 3000 centigrade situation,the moudulus will increase with the temperature…
Carbon carbon composite material is carbon fiber reinforced carbon matrix composite material,and it has a series of good properties,such as light weight,high specific strength,high specific modulus,high thermal resistance,low coefficient of thermal expansion,excellent friction property,and designable,the material now is already widely used for the nose cone and wing leading edge of space shuttle,nozzle throat and exit cone of SRM, nose-tip of missile,aircraft brake disc and high thermal mould etc. Punctured structure carbon carbon composite material is one of the composite materials of C/C composite,the good properties includes:good isotropy property,strength property. And the strength property is mainly decided from the structure of carbon fiber perform. The X-Y direction of the punctured structure perform includes carbon fiber cloth and the carbon fiber net,make…
Graphite crucible for everyone, perhaps not strange, many people may have heard of it, but they don’t understand the specific usage of the graphite crucible, today we , as the professional manufacturers will share with you and tell you what does the graphite crucible do. Simply speaking ,graphite crucible is a heated container, in our daily lives, some of the objects will melt when we heat it and it take us have a lot of trouble, for example, we can not use aluminum vessel in the melting process of iron because the melting point of iron is high than aluminum, the things which we want to melt did not be melted, but the container melt . So at this time…
