Carbon carbon composite material are carbon matrix composite material reinforced by carbon fiber and its fabric. With the advantages such as low density (<2.0g/cm3), high strength, high modulus, high thermal conductivity, low expansion coefficient, good friction performance, good thermal shock resistance and high size stability.It is a few alternative materials in above 1650℃ application now , the theoretical maximum temperature as high as 2600℃. So it is considered to be one of the most promising high temperature materials. Carbon carbon composite consist of three different components, namely, resin carbon, carbon fiber and pyrolytic carbon. Because it is almost entirely composed of elemental carbon, it can withstand extremely high temperatures and a great heating rate. By means of reinforcing the orientation…
Graphite crucible has a very wide range of application in the metallurgical industry. It is used for containing various liquid metal, as a manufacturer of metallurgy, we should know how to use graphite crucible, otherwise there will be some problems in the latter part of the production and application. Here we will introduce the matters which we should pay attention to: 1).Although the quality of graphite crucible is very good, not easy to damage, but we should handle it with care . The impact of falling from high altitude or bumps on the quality is not very big, but it will has crevice and even be broken for a long time so go on. We can’t give any remedy once…
Chopped carbon fiber is made up of carbon fiber filament cut through a short cut, its basic properties are mainly determined by the properties of the carbon fiber filament. Carbon fiber is a kind of fibrous carbon material. It is a kind of strength stronger than steel, density higher than aluminum, corrosion resistance stronger than stainless steel, heat resistant higher than steel, and can be as conductive as copper, with a lot of valuable electrical, thermal and mechanical properties of new materials. Carbon fiber is mainly made of carbon fiber reinforced plastics. Carbon fiber has the flexibility of ordinary textiles, and can be processed into fabric, felt, mat, tape, paper and other materials. Traditional use of carbon fiber in addition…
