Wear And Friction Of A Unidirectional Carbon Fibre-Glass Matrix Composite Agianst Various Counterparts

A fundamental study was made of the dry sliding and abrasive wear behaviour of a unidirectional carbon-fibre-reinforced glass matrix composite at ambient temperature. The wear rates and friction coefficients against different metals and SiC papers were experimentallly determined and the resulting wear mechanisms were microscopically observed. Three principal sliding directions relative to the dominant fibre orientation in the composite were selected. When sliding took place against smooth hard metals, the highest wear resistance and the lowest friction coefficients were observed in the antiparallel direction.
