Abstract

The impact strength, energy absorption, and failure modes of hybrid sandwich panels with corrugated aluminum core and laminated composite face-sheets are investigated. Numerical simulation of hail impact of hybrid sandwich panels is presented using LS-DYNA software. The effects of hail projectile shape, face-sheet stacking sequences, and reinforcement type on the impact response of sandwich panels are investigated. The standard test specimens of the composite face-sheets are manufactured and experimentally evaluated to obtain required mechanical properties of the lamina for hail impact simulation. The results presented herein revealed that 90 =745 =0 ½ s laminated composite face-sheets achieved the lowest damage. The hail projectile with sharper nose created higher damage on hybrid sandwich panels. The glass/epoxy face-sheets of corrugated core hybrid sandwich panel presented a significant improvement in impact response and failure modes compare to carbon/epoxy.
