Abstract:

The durability of FRP in different corrosive environment has been widely concerned and studied. In this paper, the tensile properties of FRP bars such as aqueous solution immersion, salt solution erosion, acid solution, alkali solution, and freeze?thaw were analyzed comprehensively under different action media and modes, and their evolution law of tensile strength was summarized. Based on the degradation mechanism of tensile strength of FRP bars and the Arrhenius equation, the parameter characteristics of the prediction model and equation for the tensile strength life of FRP bars under different action modes were discussed.

Key words: fiber reinforced polymer bar, corrosion environment, mechanical property, durability, life prediction model
