Abstract：Based on the virtual test method, a meso-scale finite element model was developed and proposed to investigate the influences of the cell wall thickness on impact responses and damage of the Nomex honeycomb sandwich panels. Through the analysis, it was found that that the higher resin content, the greater the impact force peak. The core absorption energy increased with the resin layer thickness as the impact energy was not high enough to penetrate the top face-sheet, however, the impact depth decreased greatly with the resin layer thickness as the impact energy was high enough to perforate the top face-sheet. Increasing resin layer thickness can significantly improve the penetration resistance of the Nomex honeycomb sandwich, while that has little effect on the damage area.
