为了研究不同树脂基体的老化特性，对常见的3种树脂开展了吸水性试验和耐水性加速老化试验，并对树脂在每个老化试验周期下分别开展压缩特性试验研究。研究结果表明，430LV乙烯基树脂吸水率为0.076%，3201乙烯基脂树脂吸水率为0.168%，350环氧树脂吸水率为0.213%；在常规试验中，3种树脂压缩载荷/位移曲线变化规律基本一致，整体呈现线弹性阶段→屈服平台阶段→屈服强化三阶段变化规律；在老化试验各个周期的湿热吸水和后固化联合作用下，3种树脂压缩载荷/位移曲线变化规律与常规压缩试验一致，但剩余压缩强度保留率差别较大。
In order to study the aging characteristics of different resin matrix, the water absorption test and the water resistance accelerated aging test were carried out for the three common resins, and the compression properties of the resin were studied respectively under each aging test cycle. The results show that：The water absorption of 430lv vinyl resin, 3201 modified epoxy vinyl resin and 350 epoxy resin were 0.076%, 0.168% and 0.213%, respectively.In the conventional test, the compression load / displacement curves of the three resins are basically the same, showing a three-stage change law: linear elastic stage → yield platform stage → yield strengthening stage; Under the combined action of hygrothermal water absorption and post curing in each cycle of aging test, the change rule of compression load / displacement curve of three resins is consistent with that of conventional compression test, but the residual compressive strength retention is quite different.
