Advance in research on tribological behavior and mechanism of carbon/carbon composites

Due to its excellent tribological properties, carbon/carbon composites were employed as aircraft brake material. Its tribological behavior was dramatically affected by both the tribotesting environment and the techniques used for the preparation of carbon/carbon composites. The factors affecting the tribological properties of carbon/carbon were discussed. The mechanisms of friction and wear were reviewed. The existing problem and the future research direction also were pointed out.
