摘　　要：考察了氙灯人工气候老化对E玻璃纤维/乙烯基酯树脂复合材料性能的影响。采用静力学性能试验研究了老化对复合材料强度的影响;采用DMA分析了老化对复合材料储能模量和损耗模量、Tg、损耗因子tanδ的影响;采用FTIR分析了纯树脂和复合材料老化后的吸收峰和峰强的变化;采用SEM分析了老化对其损伤的影响、及损伤和疲劳应力间的关系。发现,氙灯人工气候老化的主要影响因素是紫外辐射;纤维促进了树脂基体的交联和降解。The effects of artificial xenon arc lamp ageing on E-glass/vinyl ester composite were investigated.The mechanical properties of the composite are investigated by static mechanical tests,the storage and loss moduli,Tg, the peak of tanδby DMA,the peak location and peak intensity by FTIR for pure resin and the composite,and fracture development and the relationship between fracture density and fatigue stress level by SEM,respectively.It is found out that the most significant ageing factor is ultraviolet radiation,and that the introduction of glass fiber will accelerate the crosslink and degradation of resin.
