| 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。

| Abstract: | In order to study the impact resistance of composite with different layer modes, two kinds of laminates that unidirectional 0°]8and 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-time curves were obtained to analyze low-speed impact with loading mechanical performance of two kinds of laminates. The damage mode of compositelaminatewasobtainedtoanalyzeitsdamagingmanners.Theresultsshowthatthetwolayermodeshaveadifferent damagingmanners,thelow-speedimpactresistanceofthecrossply0/90]2s laminateisbetterthanthatofunidirectional0°]8 laminate. |
