TRIBOLOGICAL PROPERTIES OF RESIN-BASED FRICTION MATERIALS REINFORCED BY NANOPARTICLES
摘要
Abstract
By employing phenolic resin modified by NBR as matrix, kevlar and glass fiber as reinforced fibers, different types of nanoparticles were selected to design the formula for the friction material, which was prepared by hot pressing sintering technology. The tribological properties of the materials were tested by the friction and wear testing machine under dry friction conditions, and the surface of friction materials was observed by scanning electron microscopy ( SEM), based on which the effect of different nanoparticles on friction material properties was studied. The result shows that under dry friction, the friction material modified by nanoparticles has a higher friction coefficient, hardness and a lower wear rate than the unmodified material. The friction coefficient and wear rate of materials modified by nanoparticles exhibit a trend, which decrease with the increase of test load and the sliding speed. The wear mechanism of modified materials is fatigue wear and abrasive grain wear. However, the wear mechanism of unmodified material is mainly fatigue wear.关键词
