通过普通环境、碱环境和氯离子环境下CFRP的耐久性试验,研究腐蚀环境对CFRP的力学性能的影响。试验结果表明,碱环境下CFRP抗拉强度有下降趋势,弹性模量和极限应变基本保持不变;氯离子环境下,CFRP抗拉强度和弹性模量有增加趋势,极限应变基本保持不变。
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 remained hasically 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.
