Etude et réalisation d’une solution composite à renfort tissé interlock pour la protection balistique de véhicule

Abstract : This thesis was performed at the laboratories of GEMTEX and LAMIH on study and evaluation of a solution based on warp interlock reinforced composite for vehicle ballistic protection. The main purpose of this thesis is to explore the potential of warp interlock reinforced composite solutions in the case of a high velocity impact. We have chosen to study two composite solutions manufactured in our laboratory which presented the same warp interlock reinforcement but with different resins and infusion processes. Those composites were tested by an FSP (Fragment Simulating Projectile) impact as armour backing. Few campaign of tests were performed which helped us to optimize our warp interlock structure in order tohave a better response to the dynamic loading. The impact results of our composites have been compared with those of the benchmark which is a composite generally used backing. Thanks to these tests we had the possibility to observe that one of our structures present a better impact behaviour than the others. In order to improve our representation of those reinforcement, we have been working on the numerical modelling of those warp interlock submitted to impact. Innovative numerical models have been set up thanks to micro-tomography analysis allowing a more realistic representation of the reinforcement.
