Experiments are described which examine the effect of reinforcement by carbon fibres on the friction and wear of polyester resin sliding either against itself or tool steel. It is shown that reinforcement can significantly reduce both the coefficient of friction and the rate of wear, the maximum effect being achieved when the fibre axes are oriented normal to the sliding surface. In these conditions it is suggested that the fibres act as preferential load-bearing contact regions.
