【Abstract】 The friction and wear behaviors of potassium titanate whiskers modified bismaleimide resin under different coupling agent and whisker content were investigated. The results show that wear resistance can be improved and the wearing ratio of the composites decrease markedly by adding potassium titanate whiskers. The friction coefficients of the composites are corresponding wit the resin matrix. Coupling agents have no notable influence on the friction coefficient. However, appropriate coupling agent can improve wear resistance remarkably. At a relatively lower whisker content, the wear of the composites is characteristic of adhesion. While at higher whisker content, it is dominated by fatigue.更多还原
