High energy absorption of warp interlock fabrics: Application to high speed impact of fragments

Abstract
3D textiles composites have a vast range of properties that can be superior to traditional 2D laminates. Warp interlock fabrics are generally defined into three main types as layer to layer, angle and orthogonal. Each of them can be used in different applications depending on their properties. In this work, the energy absorption capability of three samples through impact tests has been studied. The identification of the best structure which could potentially be used as a protection system against fragments was the main goal. Single fragment shots were performed with the help of a powder gun while impact and exit velocities were measured and compared.
