The tensile properties of fiber-reinforced composites (FRP) under various factors of composite aging were studied by tensile test. The test parameters mainly include temperature, salt spray, ultraviolet, rainwater, and stress. The results show that the higher the temperature, the faster the FRP tensile strength decreases; At the same temperature, the ultraviolet radiation has little effect on BFRP bars. Salt spray and rainwater hydrolyze the resin on the surface of the steel bars and expose the inner steel bars. Stress can accelerate the degradation of tensile properties of FRP bars. It has little effect on the elastic modulus of FRP bars. A scanning electron microscope (SEM) was used to observe the changes of steel bars and the mechanism of mechanical property degradation was studied
