The influeces of glass transition temperature (T_g) of epoxy resins filled with graphite fluoride (C_2F) _n powders (C2F) in the range 0〜30 wt%, on friction and wear properties were investigated. The epoxy resins used for matrices were Tetrad^R D and X (ER-D and X) cured with HHPA, the T_g of which measured by Rbeovibron at 110Hz were 246℃ and 236℃, respectively. It was observed by SEM photographs that the C2F particles were dispersed randomly in the composites. The limiting pV values of ER-D and X filled with 30wt% of C2F powders were higher than that of Epikote^R 828 (ER-E) filled with 30 wt% of C2F by 8.2 times. The friction coefficients (μ) of the composites were in the range of 0.1〜0.2. The specific wear rates (W) of the composites were in the order of 10^<-5> mm^3/kg・mm and were lower than that of ER-E filled with C2F by l/10 times. The limiting pV values of the composites which were filled with 30 wt%of C2F treated with coupling agents were larger than those of the composites filled with untreated C2F by 1.4 times.
