Abstract:

Based on the durability test of CFRP in ordinary,alkali and chloride environment,the influence of corrosion environment on mechanical behavior of CFRP is studied.Test results indicate that CFRP subjected to al- kali environment shows that the tensile strength has the tendency of degradation,the modulus and ultimate strain re- mained basically unchanged|CFRP subjected to chloride environment shows the tensile strength and modulus of CFRP has the tendency of increase,the ultimate strain remained basically unchanged.

Key words: fiber reinforced polymer, durability, mechanical behavior, experimental study
