Carbon fiber reinforced carbon and ceramic dual-matrix composites (C/C-SiC) have the characteristics of low density (≤2.5g/cm3), high-temperature resistance (to 1 600℃), good oxidation resistance, corrosion resistance, and excellent friction and wear resistance. As high-performance friction materials, C/C-SiC composites present a promising application potential in the fields of high-speed and heavy-duty equipment. Recent work on the preparation methods, microstructure design, friction and wear mechanism, modification and application of C/C-SiC friction materials were summarized, and the prospects for development of C/C-SiC composites were also proposed.
