Applications and development of fiber-reinforced polymer in civil engineering

As a new kind of high performance composite material, FRP(Fiber- reinforced polymer) has been widely used in different fields. Many research works and applications of FRP in civil engineering were carried out by both domestic and international experts in recent years, and made a breakthrough. This paper mainly introduces the different forms of FRP and properties frequently used in civil engineering, analyzes advantages and drawbacks of FRP. An introduction is given on the research progress of FRP bar, FRP bars reinforced concrete structures and FRP - concrete -steel composite columns, FRP reinforcement structures, FRP structures and FRP composite structures, so as to promote FRP popularization and application in the field of civil engineering in our country.
