PREPARATION OF HIGH TRIBOLOGICAL PROPERTIES CARBON / CARBON COMPOSITES
高摩擦学性能碳／碳复合材料研制

The process prepared of high tribological properties (HTP) C/C composites was explored,the mode of microstructure of HTP C/ C composites was designed, C/C composites that possess microstructure with spherical deposition carbon on carbon fibre were developed. Experiments showed that the HTP C/C composites have better tribological properties: the variation of brake moment with velocity is stable, the peak value of starting moment is low, friction coefficient is moderate, specific wear is small, friction surface is smooth, samples are not delaminded and fractured.
