Hybridization of sandwich panels and their different components have drawn huge attention due to the significant improvement in their attributes. Hybrid core of ‘Polyester Pin-reinforced Foam filled Honeycomb Sandwich panels’ (PFHS) were fabricated and compared with unreinforced ‘Foam filled Honeycomb Sandwich panels’ (FHS) in terms of low velocity impact and Compression After Impact (CAI) performance. The impact damage area was calculated by employing MATLAB image processing technique. Incorporating through thickness pins for connecting faces and core is an effectual way to improve interfacial bonding, specific bending stiffness and also imparts out of plane properties for sandwich panels. The low velocity impact tests performed on the sandwich panels revealed that the polyester pin reinforcement in foam filled honeycomb sandwich panel improved the load bearing capacity, total absorbed energy and reduced the impact damage area significantly. In CAI test, debond, wrinkling of face sheet, and buckling of face sheet and core are the major modes of failure. The addition of the pins enhanced the compressive strength for all the impact energy levels.

夹心板及其不同组件的杂交由于其属性的显着改善而引起了极大的关注。制造了“聚酯针增强泡沫填充蜂窝夹芯板”（PFHS）的混合芯，并在低速冲击和冲击后压缩（CAI）性能方面与未增强的“泡沫填充蜂窝夹芯板”（FHS）进行了比较。利用MATLAB图像处理技术计算出冲击损伤面积。并入用于连接面和芯的厚度销是一种有效的方法，可以改善界面粘结，特定的弯曲刚度，并且还可以为夹心板提供平面外特性。在夹心板上进行的低速冲击试验表明，泡沫填充蜂窝状夹心板上的聚酯销增强了承载能力，吸收了总能量，并显着减小了冲击破坏面积。在CAI测试中，面板的脱粘，起皱以及面板和型芯的弯曲是主要的​​破坏方式。销钉的添加提高了所有冲击能级的抗压强度。
