This study presents microstructure and friction-wear properties of pitch-based C-C composites prepared by a vacuum impregnation-atmospheric carbonization (VICA) and a hot isostatic pressure impregnation-carbonization (HIPIC) process. For the VIAC process the density was 1.79g/cm3 after 5 times of densification cycle. On the other hand 1.83g/m3 only after 3 times of densification cycle by the HIPIC. The VIAC C-C composites. showed high friction coefficient and wear rate due to a low hardness as a result high crystallinity of the composites. In the VIAC C-C composites the friction coefficient and the rate decreased with increasing sliding velocity and normal load for all friction condictions except the condition of 123.3N-5.86 msec-1 where the wear rate increased rapidly by an oxdation wear that was resulted from a high friction temperature at this condition
