摘要：
In order to improve the performance of non-asbestos composite auto brake pads that are composed of matrix resin, reinforced material and fillers, a novel method with new technology of self-heal microcapsules was proposed. Nano reinforced fillers’ effects were also considered in the experiment project. Five recipe designs for new composite auto brake pads were carried out and corresponding samples were prepared as well. The friction coefficient and wearing properties at certain temperature, impact intensity and hardness were comparatively studied. Investigations indicate that properties of such composite auto brake pads meet the requirements of the national standards while microcapsule’s weight content varies from 5.5wt%–1.09wt% of matrix resin and microcapsule’s location varies in the pads. Nano reinforced fillers have the effects of increasing composites’ impact intensity and hardness. Application of self-healing microcapsules in auto brake pads is feasible.
