한국어 초록
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.
