The carbon carbon composite material mainly consists of carbon fiber and carbon matrix two parts. The rational design can control the strength,thermal and physical properties of the carbon carbon composite material etc. and make it meet the production requirement on the direction and dimension. The function of the carbon matrix is fix the structure and direction of the carbon perform, and make it into continuous phase,and when it is under load,the carbon matrix can transfer the load to the carbon fiber. In addition,the carbon matrix can increase the density of the carbon carbon composite material,and reduce the porosity, it can protect the perform under the ablation and oxidation environment. The carbon matrix not only can change the properties of the…
In accordance with the requirements of the use of graphite bearings can be used in the following three ways to install. 1 shrinkage mounting method The method is mainly used in PV large bearing. It is well known that the graphite bearing has a lower coefficient of thermal expansion and elastic modulus, it is difficult to keep it firmly in the metal sleeve. Therefore, only the beginning of high tolerance to go in, for this, the cold state bearings can be loaded into a pre heated to a certain temperature of the metal sleeve. The preheat temperature should not be less than the maximum operating temperature. The metal sleeve is then cooled to shrink, so that a certain pressure is…
What is graphite products? What are the characteristics of graphite products? What graphite products can be made from ordinary graphite? let me tell you one by one. Graphite products are made of synthetic graphite and natural graphite according to the properties of the graphite. The characteristics of graphite products have are as following: 1).Graphite products have excellent adsorption. The open space structure of carbon has excellent adsorption, so carbon is often used as adsorption material for the adsorption of water, odor, toxic substances, etc.. 2).Graphite products have excellent thermal conductivity, fast heat transfer, uniform heating, fuel saving. 3).Graphite products have the abilities of chemical stability and corrosion resistance. Graphite has excellent chemical stability at room temperature, without any corrosion of…
