Composite Sandwich Structures for Shock Mitigation and Energy Absorption

Abstract

Analytical models for the blast response of navy composite and composite sandwich structures were developed in this research grant. This report summarizes research spanning two consecutive grant periods of performance: February 2011 to June 201 4 and July 2014 to April 2016. A common theme in the analysis of the blast performance of foam-core, composite sandwich panels was that on a per unit areal weight density basis, lighter and more crushable foam cores offered greater blast resistance and energy absorption than the heavier and stronger foam cores. This was found to be the case even on an absolute weight basis for curved sandwich panels and panels subjected to underwater blast.
