| 摘 要： | 采用玻璃纤维增强环氧树脂复合材料层合板作为内、外面板，以PVC泡沫作为芯材，构造了双层夹芯复合材料结构。采用落锤冲击实验，得到了冲击过程的撞击力历史；研究了在不同的冲击能量下，双层夹芯结构的冲击响应及内面板位置对双层夹芯结构冲击响应的影响。实验结果表明，内面板的引入及内面板的位置显著影响双层夹芯结构的撞击力历史，根据该撞击力历史可以优化设计出抗冲击性能优异的新型双层夹芯复合材料结构。

| Abstract: | Traditional single core sandwich structures consist of two face sheets and one core.With an additional sheet,called internal sheet in this paper,inserted into the core,a two-core sandwich structure was then formed.Two-core sandwich structures with glass fiber/epoxy composite laminated face sheets and a thin internal sheet subjected to low velocity impact were studied,and attention was focused on the contact force responses of the two-core sandwich structures and effects of the locations of the internal shee... |
