摘　　要：为了验证表面铺覆芳纶纤维铺层降低碳纤维层合板冲击损伤的有效性,对环氧树脂基芳纶/碳纤维层间混杂层合板和非混杂碳纤维层合板进行了冲击试验研究。结果显示:8克弹丸以速度为276～366 m/s的冲击条件下,入射面铺覆芳纶可减小出射面和内部分层的损伤面积;出射面铺覆芳纶可减小出射面损伤面积,但会造成严重的混杂界面分层。为了减小碳纤维层合板的弹丸冲击损伤程度,可在冲击正面铺覆芳纶纤维层。The bullet impact damage of Kevlar-carbon/epoxy hybrid laminates and carbon/epoxy composite materials were studied.The steel projectiles(weight 8 g)were propelled with gas gun,and shoot from different side of hybrid laminates and non-hybrid laminates at different speeds(276~366 m/s).The results showed that the damage range could reduce under bullet impact,while carbon fiber laminates was covered with Kevlar layers;but Kevlar layers were avoid to be covered bullet′s exiting surface,in order to reduce the delamination damage in hybrid interface.
