研究了泡沫铝夹芯混杂复合材料夹层梁在准静态载荷和低速冲击下的变形和破坏。夹层梁包括两个碳纤维增强塑料（CFRP）面板，具有相同/不相同的厚度。试验结果表明，混杂复合材料夹层梁具有四种主动破坏模式：面板断裂、压痕、芯层剪切和芯层剪拉。两个相同面板的夹层梁发生核心剪切，而两个不同面板的夹层梁发生核心剪拉。对于相同的顶面板和底面板总厚度，具有较厚顶面板的非对称夹层梁具有比具有较薄顶面板的非对称夹层梁上级的承载能力。对于混杂复合材料夹层梁在准静态载荷和低速冲击下相似的破坏模式，低速冲击破坏载荷高于准静态破坏载荷。用简单的理论解预测的混杂复合材料夹层梁的破坏荷载与实验值吻合较好。
The deformation and failure of hybrid composite sandwich beams with an aluminum foam core under quasi-static load and low-velocity impact are investigated. The sandwich beams comprise of two carbon fiber-reinforced plastic (CFRP) face sheets which have identical/unidentical thicknesses. The experimental results show that hybrid composite sandwich beams exhibit four active failure modes: face-sheet fracture, indentation, core shear and core shear-tension. Core shear occurs in sandwich beams with two identical face sheets, while core shear-tension develops in sandwich beams with two unidentical face sheets. An asymmetrical sandwich beam with a thicker top face sheet has superior load-carrying capability than those with a thinner top face sheet for the same total thickness of the top and bottom face sheets. For the similar failure modes of hybrid composite sandwich beams under quasi-static load and low-velocity impact, the low-velocity impact collapse load is higher than that corresponding to quasi-static collapse. The collapse loads of hybrid composite sandwich beams predicted by simple theoretical solutions are in good agreement with the experimental values.
