【摘要】 通过快速冻融试验、耐碱性试验、浸水试验、湿热暴露试验、人工加速老化试验,研究了腐蚀环境对纤维增强复合材料(FRP)的复合体及粘结剂力学性能的影响.结果表明:碳纤维增强复合材料(CFRP)的耐久性能较好,在各种暴露条件下,其力学性能没有明显退化;玻璃纤维增强复合材料(GFRP)的耐久性能略差,水环境、碱环境、湿热环境以及冻融循环对其均产生了较大影响.粘结剂试件在人工加速老化曝露试验后,其外观颜色和力学性能均发生一定的变化.更多还原

【Abstract】 Based on the fast freeze-thaw test,the alkaline resistance test,the water immersion test,the wet-thermal exposure test and artificial accelerated aging test,the influence of the corroding environment on the mechanical behavior of fiber reinforced polymer(FRP) laminates and adhesive was studied.The test results indicate that carbon fiber reinforced polymer(CFRP) specimens subjected to aggressive environments shows good durability with no significant degradation in tensile strength and modulus,however,glass fiber reinforced polymer(GFRP) specimens exhibited a little decrease in mechanical property after aggressive environments exposure.The adhesive specimens shows some degree of deterioration in appearance and mechanical characteristics after artificial aging test.更多还原
