The two dimensional carbon fiber reinforced silicon carbide matrix (C/SiC) composites were prepared by a chemical vapor infiltration method. Based on the coupling stress equivalent simulation system, a characterization method with the change of torque was proposed to evaluate the friction behavior under transmitting motion. The friction and wear behavior and wear mechanism of C/SiC composites under high load and low rotation velocity based on transmitting motion were studied. Results show that a good wear resistance and load-carrying ability is demonstrated by the low friction torque, low wear rate and small material deformation under high loads. Under the same testing condition, the wear rate of C/SiC composites is only 1/10 - 1/20 of that of Ti alloy. The wear behavior on contact surface is mainly grain-abrasion mechanism under low rotation velocity, and no hot cracking is caused by the high loads during tests.
