| 摘 要： | 通过对玻纤增强环氧乙烯基酯树脂(GF/EVE)和玻璃纤维增强不饱和聚酯树脂(GF/UP)复合材料的多轴向铺层设计试件进行低速冲击、弯曲和剪切破坏性力学试验,分析了不同铺层方式的GF/EVE和GF/UP复合材料冲击、弯曲和剪切载荷作用下产生的损伤及失效模式。结果表明:在铺层设计与工艺相同的情况下,CF/EVE的弯曲强度、冲击韧性均优于CF/UP;0,90]6试件冲击能量吸收性能优于其他五种铺层方式;铺设角设计、树脂基体类型、铺层厚度对层合板剪切力学性能的影响较小。并基于SEM与超声C扫描成像检测(C-SAM)对复合材料的微观界面脱粘机制及损伤演化行为进行阐释。

| Abstract: | The experimental investigation on mechanical properties of the multi axial glass fiber reinforced epoxy vi-nyl ester resin (GF/EVE)and glass fiber reinforced unsaturated polyester (GF/UP)resin composite material were carried out.And the bending strength,interlaminar shear strength and modulus of the specimens were analyzed. The results show that,in the same layer design and process,the bending strength and impact toughness of GF/EVE resin are superior to GF/UP resin.0,90]6 specimen impact energy absorption performance is superior to the other five layer mode.And basing on SEM and micro ultrasonic C-scan imaging detection,the mechanism of the compos-ites interface debonding mechanism and damage evolution behavior were elucidated. |
