英文摘要Carbon fiber-reinforced ceramic materials are promising candidates for braking and transmission systems due to their lightweight structure, high strength, excellent high-temperature performance, and superior tribological characteristics. In this study, C/C-ZrC-HfC-SiC carbon-ceramic composites with varying ceramic contents were fabricated using a combined chemical vapor infiltration and precursor impregnation and pyrolysis process. The microstructure, mechanical properties, and tribological behavior of these composites were systematically investigated. Compared to C/C-SiC composites, the C/C-ZrC-HfC-SiC composites exhibit a synergistic enhancement in mechanical strength, friction coefficient and wear resistance. This enhancement is attributed to the reduced stress concentration arising from the interface modulus gradient effect induced by the introduction of ZrC and HfC into the matrix and their segregation near the carbon fibers. Moreover, the tribological performance of the composites is influenced by both the ceramic content and applied load, and the underlying mechanisms are elucidated. These findings provide valuable insights for the application and further optimization of carbon-ceramic composites.
