Abstract
Concrete cracking caused by steel corrosion is the main form of concrete structure deterioration at present. In order to solve the problem of steel corrosion, people begin to seek to replace steel with corrosion-resistant materials. Fiber reinforced polymer (FRP) has the advantages of high strength to mass ratio, good fatigue resistance, simple construction, corrosion resistance, etc., and has been widely used in engineering in recent years. In this paper, it analyzes the research status of FRP composites and introduces the properties of different kinds of FRP composites in detail. Then, by comparing with ordinary steel bar, the advantages of steel bar containing FRP material are highlighted. Subsequently, the durability of FRP composite materials in corrosion environment is studied. Finally, this paper introduces the practical application of FRP composites in engineering. The results are helpful to popularize the application of FRP composites in practical engineering.
