Cf/SiC composites reinforced by carbon fiber were fabricated by hot-pressing. The effects of sintering temperature on the densities, microstructure and mechanical properties were studied. Densities of the Cf/SiC composites are increased with the increase of sintering temperature, and the bending strength and fracture toughness are increased with the sintering temperature increasing from 1800℃ to 1850℃, The highest bending strength and fracture toughness of the composites fabricated at 1850℃ are 500.1MPa and 16.9MPa·m 1/2, respectively. However, when the temperature increases to 1880℃, the mechanic properties of the composite decreases.
