Effects of Humidity and Structure on Friction and Wear Properties of Carbon Fiber/Epoxy Composites

탄소 섬유/에폭시 복합 재료의 마찰 및 마멸 성질에 미치는 습도 및 구조의 영향

Friction and wear behavior of a unidirectional high modulus carbon fiber reinforced epoxy composite exposed to high and low humidity was experimentally examined with various sliding speeds. The results show that the moisture at the sliding surface greatly influences friction and wear properties of the composite. It is also discoverd that the difference in friction and wear behavior between samples with different fiber orientations is mainly due to the anisotropic properties caused by the microstructure of oriented graphite crystals in the carbon fibers and the macrostructure of fiber orientation in the matrix.
