Abstract
Carbon / graphite composite material is a high performance structure, functional composite materials with high strength, high modulus, high thermal conductivity, excellent insulation and other outstanding features. Carbon / graphite composite material is widely used in machinery, electronics, chemicals, metallurgy and other fields of nuclear energy and in the aerospace, aviation and defense in the field of critical components on a large number of applications. However, the carbon materials start to oxidize in the atmosphere 450 ℃, In the mild oxidation, materials, density and strength are decreased. When Severe oxidation, material stratification occurs, complete lose mechanical properties. The design prepared by physical and chemical properties and good mechanical properties of carbon / graphite composite materials for the purpose of carbon / graphite composite materials, adhesive agents and their properties were modified system. Change the ratio of raw materials were used and the type and amount of change in method of binder obtained bulk density and mechanical strength of carbon / graphite composites. By contrast the use of familiar materials, petroleum coke prepared its density, mechanical strength and electrical conductivity of petroleum coke used to be good students. With phosphoric acid, silicon carbide modified phenolic resin, its performance is stronger.
