Carbon ceramic composite (C/SiC) is a carbon fiber reinforced silicon carbide ceramic composite. The main matrix component of silicon carbide determines the hardness of the composite, the effect of carbon fiber is to improve the mechanical strength and fracture toughness of the material, and its strength is 5 times higher than that of the steel.
The carbon ceramic composite material has the advantages of low density, high temperature oxidation resistance and corrosion resistance, and is a new type of high temperature structure material and functional material which can meet the use of 1650 degrees centigrade. Carbon ceramic composite materials will become a new generation of aircraft and automotive brake materials.
There are 3 ways to produce carbon ceramic composite material:
- Liquid Silicon Infiltration (LSI).
- Polymer Impregnation and Pyrolysis (PIP)
- Chemical Vapor Infiltration (CVI)
Each way of production has its own characteristics, and the properties are little different.
Compared with carbon / carbon composites, carbon / ceramic composites have better oxidation resistance. C/SiC ceramic matrix composites have the advantages of high temperature resistance, low density, high strength, high thermal conductivity, high wear resistance, high damping coefficient, high thermal radiation coefficient, performance can be designed strongly and so on.
The application fields of carbon / ceramic composites:
Aerospace thermal protection system, carbon ceramic composite material is one of the best candidate materials of making the ablation surface resistance thermal insulation board. In the field of aerospace, when the vehicle enters the atmosphere, due to the large amount of heat produced by friction, resulting in the aircraft suffered serious erosion, it needs an effective thermal protection system such as the space shuttle and missile nose cone, wing, wing and cover plate, etc…in order to reduce the erosion of the aircraft.
The high temperature connector, in a development project in Europe, advanced connection technology of thermal structure material has been developed very quickly, connecting with carbon ceramic composite material thermal structure, it can prevent the supersonic airflow interference, and also can seal under the high temperature, the simulation test results show that connections can be applied to the actual environment of high temperature, and can meet the necessary flight standards.
The carbon ceramic composite brake system, on the highway, it often occur large trucks, buses and cars collision because of the brake failure so that cause fatal accident and vehicle damage. Generally, except the human factors, the main reason is the brake overheating, especially heavy truck long distance downhill,the strength of brake pad material decline sharply under the high temperature, it will result in brake failure and lead to disaster. As a result, we drip the water to the wheel shaft constantly to cool the brake pad when the large trucks run long distances. The use of new carbon ceramic composite materials will be an effective means to solve this problem.
