英文摘要： Large amounts of fly ash generated from coal-fired power plants have caused serious pollution to the environment. Based on the direction of tribology research of fly ash cenospheres added in polymeric materials and the exploration and development of its more valuable approaches, and the epoxy resin matrix composites as erosion resistant protective coating has been used increasingly in the field of erosion wear, this project puts forward an industrial solid waste, high-alumina fly ash cenospheres, as a reinforcement to epoxy-based composites. The erosion wear behavior of fly ash cenospheres-epoxy composites will be drawn up, then the theory model of cenospheres size gradation will be established through the study on the distribution of particle size. Started with the modified mechanism of cenospheres and the interface bonding mechanism between cenospheres and epoxy-based composites, the functioning mechanism of cenospheres on the curing behavior of the epoxy resin will be studied. Then the relationship between the curing of cenospheres/ epoxy system, the interface bonding between cenospheres and epoxy-based composites, the mechanical properties and the slurry erosion wear resistance of cenospheres/ epoxy composites will be comprehensively analyzed. And the slurry erosion wear mechanisms of cenospheres/epoxy compo
