FRP, fiber reinforced composite plastic, is an abbreviation of English (Fiber Reinforced Plastics), existing CFRP, GFRP, AFRP, BFRP and so on. In Chinese, FRP refers to GFRP. The FRP composite material is a high-performance material formed by mixing a fiber material and a matrix material in a certain ratio. Among them, GFRP has different types of resins, such as polyester glass reinforced plastic, epoxy glass reinforced plastic, and phenolic glass reinforced plastic. Generally, FRP is light and hard, non-conductive, high in mechanical strength, less in recycling, and resistant to corrosion.

With the advancement of social science and technology, the development of the discipline of civil engineering structure has benefited to a large extent from the application and development of new materials and new technologies with excellent properties, while FRP has excellent mechanical properties and adapts to modern engineering structures. The demand for large span, towering, heavy load and light development is being widely used in bridge engineering, various civil buildings, marine engineering and underground engineering, and has been widely concerned by the structural engineering community.
