1,development history of high-performance brake materials
Carbon ceramic composite brake materials developed in the 1990s, is a kind of high strength carbon fiber as the reinforcement, pyrolytic carbon, silicon carbide (SiC) as the matrix of multiphase composite brake material.
On the basis of carbon/carbon composite brake materials, silicon carbide (SiC) ceramic hard material with excellent oxidation resistance is introduced as a brake material, which not only maintains the advantages of low density and high temperature resistance of carbon/carbon composite brake materials, but also overcomes the disadvantages of carbon/carbon brake materials such as low static friction coefficient, large wet decay, short friction life and poor environmental adaptability. As a new generation of brake materials, it has a broad application prospect in the braking field of modern vehicles such as automobiles and high-speed trains.

Advantages of carbon ceramic brake disc
Due to the high cost, carbon carbon composite is mainly used in aircraft brakes. With the development of high-speed railway in recent years, domestic and foreign science and technology workers began to develop carbon pottery composite friction pair for high-speed railway. Carbon pottery composite is a kind of internationally focused friction pair material. It is expected to become the main development direction of brake products.
Comparison of main parameters between carbon ceramic brake disc and traditional brake disc
The main matrix component of carbon/ceramic composite is silicon carbide, which has the advantages of high temperature resistance, high strength, oxidation resistance, corrosion resistance and impact resistance. The carbon ceramic disc has obvious advantages over the ordinary brake disc.
