通过在单蜂窝芯中插入中间面板而形成的双蜂窝夹芯板在屏蔽空间碎片超高速冲击方面表现出比单蜂窝板更好的能力。采用质点法和基于点的内部结构模型对双蜂窝芯屏蔽结构进行了深入研究。前蜂窝芯和后蜂窝芯错开，以获得更好的屏蔽效果。研究发现，交错的双蜂窝芯比原来的双蜂窝芯更能击碎碎片并减少冲击威胁。后面板上的孔尺寸大大减小，并且面板在某些冲击速度下不会穿孔。交错的双蜂窝板可以作为超高速撞击的新型有效屏蔽结构。
The double honeycomb sandwich panel, which was formed by inserting an intermediate facesheet into single honeycomb core, showed better capability than single honeycomb panel in shielding hyper-velocity impact from space debris. Shielding structures with double honeycomb cores are thoroughly investigated with material point method and point-based internal-structure model. The front honeycomb core and the rear honeycomb core are staggered to obtain better shielding effect. It is found that staggered double honeycomb cores can fragment the debris and lessen impact threats much more than original double honeycomb cores. The sizes of the holes on the rear facesheet are greatly reduced, and the panels are not perforated for some impact velocities. Staggered double honeycomb panels can be adopted as novel effective shielding structures for hypervelocity impacts.
