Carbon/epoxy woven composites are prominent wear-resistant materials due to thestrength, stiffness, and thermal conductivity of carbon fabric. In this study, the effect of oilabsorption on the wearbehaviors of carbon/epoxy woven composites was investigated. Wear tests were performed ondry and fully oil-absorbed carbon/epoxy woven composites. The worn surfaces of the test specimenswere examined via scanning electron microscopy to investigate the wear mechanisms of oil-absorbed carbon/epoxy woven composites. It was found that the oil absorption rate was 0.14% when the carbon/epoxy woven composites werefully saturated. In addition, the wear properties of the carbon/epoxy woven composites were found to beaffected by oilabsorption. Specifically, the friction coefficients of dry and oil-absorbed carbon/ epoxy woven composites were 0.25-0.30 and 0.55-0.6, respectively. The wear loss of the oilabsorbed carbon/epoxy woven composites was 3.52 × 10-2 cm3, while that of the dry carbon/ epoxy woven composites was 3.52 × 10-2 cm3. SEM results revealedthat the higher friction coefficient and wear loss of the oil-absorbed carbon/epoxy woven composites can beattributed tothe existence of brokenand randomly dispersed fibers due to the weak adhesion forces between the carbon fibers and the epoxy matrix.
