The effect of a post-treatment comprising reimpregnation of a carbonaceous additive-doped liquid precursor on tribological performance of a fastcarbonized PAN/phenolic-based C/C composite has been discussed in a previous study. According to the study, after the post-treatment, all samples demonstrate decreases in both COF (coefficient of friction) and weight loss. The results indicated that an appropriate post-treatment may dramatically improve the tribological performance of the PAN/phenolic-based C/C composite. The purpose of the present study is to verify whether this simple treatment is also capable of improving the tribological performance, especially reducing wear rate of two other 2D C/C formulae (PAN/CVI and pitch/phenolic/CVI), which are among the most popularly used C/C composites for aircraft brake disk today. Preparation methods and properties of the pitch/phenolic/CVI (designated "A") and PAN/CVI (designated "B") composites have been described in an early study.
