Carbon fiber reinforced silicon carbide composites (C/SiC) have low density and thermal expansion coefficient, and excellent resistance to wear and oxidation, and they have become one of the important materials for braking systems. However, there are few reports on the friction- and wear-performance for friction-pairs of identical C/SiC material, resulting in the lack of reliable theoretical support in engineering design. In this work, needle-punched weftless and needle-punched nonwoven composite materials of C/SiC (with SiC content of 60% and 75%, respectively) were prepared by improved reaction melt infiltration through the ceramization of micro-nano porous carbon. The influence of preform structures and testing temperatures (25, 200, 400 and 500 ℃) on the friction- and wear-performance for friction-pairs of the two C/SiC composite materials respectively were investigated by means of X-ray diffraction, scanning electron microscopy and laser scanning confocal microscopy after high-temperature pin-disk friction and wear tests. The results show that with the increasing temperatures, the friction coefficients of the two C/SiC composite materials first increase and then decrease until they stabilize, while the wear rates first decrease and then increase. Such behaviour may be ascribed to that the abrasive wear occurs at lower temperatures on the materials surface, while the formed wear debris fill in the surface depressions resulting the friction film formation, and thus frictional resistance decreases; with the further increasing temperature the fatigue wear may emerge, resulting in the alternative formation and detachment of friction films. In addition, when the temperature reaches up to 500 ℃, compared with the needle-punched weftless C/SiC, the needle-punched nonwoven C/SiC composite has a higher friction coefficient of 0.53 and lower wear rate of 710.7 mg/cycle, suggesting better friction and wear performance. It is due to the higher content of SiC in the needle-punched nonwoven C/SiC composite.
