IMPACT BEHAVIOUR AND RESIDUAL STRENGTH OF HONEYCOMB STRUCTURES

Abstract

The goal of this article is to study the behavior of sandwich structures with honeycomb core during and after an impact. In this purpose, a test program was created and afterwards was applied. It consists in the application of multiple impact energies over the multi-layered structure. Impacted specimens are subjected to a compression test in order to determine the load capacity after impact. The results are summarized at the end of the paper in a graph that shows the loading capacity of multi-layer structure depending on the impact energy.
