The dynamic response of the sandwich panel subjected to the impact load

Abstract

In this study, the dynamic behavior of the sandwich panels subjected to the impact load are investigated experimentally and numerically. For this purpose, the sandwich panels are manufactured using the honeycomb core material and laminated composite face sheets. The face sheet materials used in this study are manufactured using an aramid fabric and epoxy resin. The wet hand lay-up technique is used to produce the sandwich panel. The curing is achieved by using a heated vacuum table. The panel is fixed at all edges and the impact load is applied on the panel. The dynamic response of the panel is measured using the strain gauges. The panel is also modeled using Ansys finite element software. The analysis of the impact test is achieved. The numerical and experimental results are compared. The results are found in an agreement. The final results are concluded.
