摘　　要：传统汽车的轻量化可显著降低燃油消耗,减少尾气排放。纯电动新能源汽车的轻量化,对提升续航里程,延长电池的使用寿命,降低使用成本更是具有重要意义。汽车制动盘作为簧下转动部件,其轻量化效果更为明显。铝基复合材料是制备轻量化汽车制动盘的关键材料之一,具有密度小、比强度和比刚度高等优点,其摩擦磨损性能是影响材料能否批量应用的重要因素。本文对国内外有关汽车制动盘用铝基复合材料摩擦磨损的研究现状进行了综述,分别介绍了铝基复合材料(增强颗粒种类、含量、尺寸、形状等)、汽车刹车片(增磨颗粒、增强纤维)以及使用工况对摩擦副摩擦磨损性能的影响,展望了未来的研究开发方向,以期为开发量产的铝基复合材料制动盘提供参考。The lightweight of traditional vehicles can significantly reduce fuel consumption and exhaust emissions.The lightweight of pure electric new energy vehicles is great for increasing the endurance mileage,improving the service life of batteries and reducing the use cost.As a rotating part under the spring,automobile brake disc has more obvious lightweight effect.Aluminum matrix composite is one of the key materials for the preparation of lightweight automobile brake disc,which has the advantages of small density,high specific strength and stiffness,and its friction and wear performance is an important factor affecting the mass application of materials.The friction and wear performance is an important factor affecting the material application.In this paper,the research status of friction and wearbehavior of aluminum matrix composites for automobile brake discs is reviewed.The influence of aluminum matrix composites(enhanced particle type,content,size,shape,etc.),automobile brake pads(grinding particles,reinforced fiber)and the effect of operating conditions on the friction and wear properties of the friction pair have been introduced.
