In daily production and life, erosive wear of solid particle flow will not only cause economic losses, but also have a security risk. Epoxy resin composite is widely used in erosive wear working conditions of particle flow due to excellent strength and erosion resistance. In order to further improve the erosion resistance of epoxy resin, fillers are usually used to modify epoxy resin. Fiber-reinforced epoxy resin exhibits excellent erosion resistance to solid particles, which facilitates broader application of epoxy resin composites. Fibers can be classified into inorganic fiber (fiber glass or carbon fiber), natural fiber and mixed fiber-reinforced epoxy resin composite. Research progress of erosion resistance of fiber-reinforced epoxy composites to solid particle flow was reviewed. Erosion behavior (plastic, brittle, semi-plastic and semi-brittle) of different fiber-reinforced composites was discussed. Characteristics of different fiber fillers (fiber category, fiber content, fiber orientation) and erosive wear resistance of reinforced epoxy resin composites under different working conditions (erosion angle, erosion rate, abrasive properties) were analyzed and compared emphatically. Erosion mode and anti-erosion mechanism of different fiber-reinforced epoxy composites were expounded, and existing problems of fiber-reinforced epoxy composites were pointed out. Finally, development directions and prospects of fiber-reinforced epoxy composites are also proposed.
