为改善铝蜂窝的力学性能，采用硬质泡沫填充铝蜂窝。这种泡沫填充的蜂窝被用来构造具有石墨/环氧树脂复合材料面板的夹层板。发现填充泡沫的蜂窝的机械性能优于未填充的蜂窝上级。低速冲击试验结果表明，含新型芯材的夹芯板具有更好的抗冲击性能，且芯材的冲击破碎高度局部化。
An aluminum honeycomb was filled with a rigid foam to improve its mechanical properties. This foam-filled honeycomb was used to construct sandwich panels with graphite/epoxy composite face sheets. The mechanical properties of the foam -filled honeycomb were found to be superior to the unfilled honeycomb. Low velocity impact test results indicated that the sandwich panel containing the new core had much improved impact resistance and that the impact-inflicted core crushing was highly localized.
