Abstract

Sandwich composites are widely used in construction of lightweight, energy resistant structures. In this study, detailed experimental results of failure and deformations in the constituents of the sandwich composites, namely, skin and core are presented and compared with the case of sandwich construction. Carbon fiber and glass fiber laminates were studied for skin materials. Balsa wood and corecell were studied for the core materials. A controlled shock tube apparatus is used to provide the high intensity shock loading to rectangular panels of the skin, core and sandwich samples. The energies during shock wave loading were estimated by the experimental data and the energy redistribution behaviors in the system were analyzed. It was observed that the sandwich construction provides the highest energy absorption with better blast resistance compared to the components. ©2009 Society for Experimental Mechanics Inc.
