FRICTION AND WEAR PROPERTIES OF ALUMINUM BORATE WHISKERS MODIFIED BISMALEIMIDE RESIN

The friction and wear behaviors of aluminum borate whiskers modified bismaleimide resin were investigated at different coupling agents and whisker contents. The results show that wear resistance can be improved by adding aluminum borate whiskers. Coupling agents have no marked influence on the friction and wear resistance, and the friction coefficient of the composite reveals increasing tendency with the prolonging frictional time. At a relatively lower whisker content, the wear of the composites is characteristic of adhesion and fatigue. When the whisker content is higher than 8%, it is dominated by fatigue, and accompanied by adhesion.
