Innovative Energy Absorbing Composite Material for Crashworthy Structures

Abstract

This research aims to develop, analyze, and evaluate a new type of structural element that will enhance the crashworthiness of naval vehicles by providing outstanding energy absorption with minimal weight. The structural element is an array of concentric fiber reinforced flexible matrix composite tubes with extension- twist coupling and ultrahigh Poisson's ratio. The tubes are configured to crush or shear internal foam as a means of absorbing energy. This interim report includes technical progress, plans, publications, and various administrative matters. In the current period, work has focused on evaluating the deformation behavior of foams and flexible matrix composites designed to crush foam as an energy absorbing mechanism during tensile loading.
