Abstract: In order to guide the optimization design of inorganic particles reinforced polymer matrix wear-resistance composites better, a comprehensive review of the effects of composite constituents on wear-resistance performance of composites was introduced. In terms of the constituents of the composites,the factors impacting wear-resistance performances of inorganic particles reinforced polymer matrix composites were classified into five parts: filler content of nano/micro inorganic particle, filler size of nano/micro particle, inorganic particle gradation with different particle sizes, synergetic enhancement of inorganic particle and fiber, inorganic particle surface treatment. The effects of each factor on wear-resistance performances of the composites were evaluated, using the view of energy, which shows the influence of each factor on external impact and friction work absorbed by fracture of internal combination bonds.Both the best particle content and the best particle size where wear-resistance performances of the composites are best are found in the part of review of the first two factors. For microparticle (particle size>50 μm), because the particle content has more influences on the wear-resistance performances of composites than the particle size, the best content should be as high as possible. But for nanoparticle, because the particle size is the key factor that influences the wear-resistance performance of composites, the best particle size should be as low as possible. Moreover, surface modification and gradation of particle can further improve wear-resistance performance of the composites, through developing the best particle content and comprehensive mechanical properties of the composites. Hybrid of inorganic particle and nano fiber can make composites have optimal wear-resistance performance, friction coefficient and good variable load adaptability.
