设计并制作了以拉伸为主的碳纤维增强Kagome晶格。夹层板是用粘合的层压皮组装的。通过面外压缩、面内压缩和三点弯曲试验对夹层板的力学性能进行了测试。揭示了夹层结构不同的破坏模式。试验结果表明，碳纤维格栅比泡沫和蜂窝格栅具有更高的强度和更高的强度。结果表明，屈曲和脱粘是夹层结构力学性能的主要影响因素，增加蒙皮厚度可能会进一步提高夹层板的整体力学性能。(C)2006爱思唯尔有限公司。保留所有权利。
Stretching dominated Kagome lattices reinforced by carbon fibers were designed and manufactured. The sandwich panels were assembled with bonded laminate skins. The mechanical behaviors of the sandwich panels were tested by out-of-plane compression, in-plane compression and three-point bending. Different failure modes of the sandwich structures were revealed. The experimental results showed that the carbon fiber reinforced lattice grids are much stiffer and stronger than foams and honeycombs. It was found that buckling and debonding dominate the mechanical behavior of the sandwich structures, and that more complaint skin sheets might further improve the overall mechanical performance of the sandwich panels.
