FRP, fiber-reinforced composite plastic, is the English (fiber reinforced polymer) abbreviation, existing CFRP, GFRP, AFRP, BFRP and so on. In Chinese, FRP refers to GFRP. FRP composites are high-performance materials formed by mixing the fiber material and the matrix material in a certain proportion. As a result of the use of different resin varieties, so there are polyester glass fiber reinforced plastic, epoxy FRP, phenolic glass fiber reinforced plastic. Light and hard, non-conductive, high mechanical strength, less recycling, corrosion resistance.
With the progress of social science and technology, the development of the discipline of civil engineering structure has benefited to a great extent from the excellent new materials and the application and development of new technology, and FRP with its excellent mechanical properties and adapt to the modern engineering structure to the large-span, towering, heavy load, lightweight development of the demand, is being more and more widely used in bridge engineering, all kinds of civil construction, marine engineering, underground engineering, is widely concerned by structural engineering.
