Processing and Elevated Temperature Strength of TiC Composites Reinforced with Carbon Fibers

TiC 20vol% carbon fiber composites were prepared using hot pressing, and the effect of sintering temperature and fiber on the mechanical properties of the composites were investigated The discontinuous carbon fibers were uniformly distributed in TiC matrix using wet ball milling mixing The suitable hot pressing temperature for C f/TiC composites was 2100℃ The strength values of C f/TiC composites at room temperature and 1400℃ were 593MPa and 439MPa, respectively, and the fracture toughness value was 6 87MPa·m 1/2 The strengthening and toughening effects of carbon fibers were evaluated
