作者针对汽车制动材料近年来的发展趋势及要求 ,在摩擦学理论及复合材料理论的指导下 ,选用片状蛭石与 kevlar纤维混杂作为增强体 ,改性树脂为基体 ,在配方及工艺研究的基础上 ,研制出片状增强摩擦材料。研究表明 :此摩擦材料力学性能高 ,摩擦性能稳定 ,特别是高温磨损小 ,噪声低 ,是一种取代石棉摩擦材料的新型制动材料。 Aiming at the development trend and requirements of automobile brake materials in recent years, under the guidance of tribology theory and composite material theory, the paper selects flake vermiculite and kevlar fiber as reinforcements and modified resin as matrix, Based on the development of flake-reinforced friction material. The research shows that the friction material has high mechanical properties, stable friction performance, especially high temperature wear resistance and low noise. It is a new type of braking material that replaces asbestos friction material.
