摘　　要：为研究复合材料不同铺层结构的抗冲击性能,采用碳纤维预浸料制备了单向[0°]8和正交[0/90]2s铺层2种不同结构的碳纤维复合材料层压板,并使用Instron 9250落锤冲击测试仪测试其低速冲击性能,得到了载荷-时间曲线,分析了2种不同铺层方式的复合材料层压板的低速冲击加载力学性能,得到复合材料层压板的破坏形态来分析其破坏方式。结果表明:2种铺层方式产生了不同的破坏模式,正交[0/90]2s的复合材料层压板的抗低速冲击能力要优于单向[0°]8铺层的。In order to study the impact resistance of composite with different layer modes, two kinds of laminates that unidirectional [0°]8 and cross ply [0/90]2s, were prepared with carbon fiber prepreg. Low-speed impact testing was performed by Instron 9250 drop weight impact testing machine. Force-tilne curves were obtained to analyze low-speed impact with loading mechanical performance of two kinds of laminates. The damage mode of composite laminate was obtained to analyze its damaging manners. The results show that the two layer modes have a different damaging mariners, the low-speed impact resistance of the cross ply [0/90]2s laminate is better than that of unidirectional [0°]8 laminate.
