In this study the energy absorption of elastomeric foam-filled aluminum honeycomb under quasi-static compression loading and low velocity impact was experimentally investigated. Commercially available Al honeycomb made of Al5052 H38 filled with elastomeric polyurethane foam was used as the specimens. Pure polyurethane had a shore hardness of 30A and to make it foam, different volume fraction of glass microballoon was added to it and a novel material was synthesized that simultaneously had the properties of elastomers and foams Energy absorption of the specimens were evaluated by different parameters such as peak load, crushing load and absorbed energy. Also, the effective failure mechanisms were fully discussed. The results showed that the addition of polyurethane to the honeycomb cells had no significant effect on energy absorption enhancement. However, the addition of glass microballoon particles to the elastomer considerably raised the maximum load, mean crushing load, and total absorbed energy and unlike conventional filled structures, it had been significantly less deformed and could act as an energy absorber against impact many times.

在这项研究中，实验研究了弹性泡沫填充铝蜂窝在准静态压缩载荷和低速冲击下的能量吸收。使用填充有弹性聚氨酯泡沫的由Al5052 H38制成的可商购的Al蜂窝作为样品。纯聚氨酯具有30A的肖氏硬度，并使其发泡，向其中添加了不同体积分数的玻璃微球，并合成了同时具有弹性体和泡沫特性的新型材料，并通过不同的参数对样品的能量吸收进行了评估，例如作为峰值负荷，压碎负荷和吸收的能量。此外，充分讨论了有效的故障机制。结果表明，向蜂窝单元中添加聚氨酯对能量吸收增强没有显着影响。
