Research progress on carbon/silicon carbide friction composite

Carbon/silicon carbide composites (C/SiC) are a new type of high performance ceramic matrix friction material developed in recent years. C/SiC composites possess a series of outstanding advantages such as low density, good oxidation resistance and a high and stable coefficient of friction. It has found a wide range of applications in the field of high energy braking for high speed trains, aircraft and heavy vehicles. The design of C/SiC friction composites, the thermodynamic conditions of the reactive melt infiltration process are analyzed. The basic characteristics and kinetic characteristics and friction and wear performances of typical short-fiber pressed and three-dimensional needled C/SiC composites are described. The application of advanced engineering detection technology such as infrared thermography, X-ray transmission and industrial computerized tomography in C/SiC friction composite component parts was also discussed.
