Numerical and Experimental Study of Multi-Layer Armors for Personal Protection

Abstract:

With continuous of the wars and the rise of the killings, taking place in the world it was necessary for us as engineers and researchers that we step even slightest to reduction in killings, and the current research is an attempt in this direction. Composite ballistic body armor materials have become a better body armor protection when contrasted with conventional steel body armor as far as its diminishment in weight and a perfection in ballistic resistance. The current research attempted to design and manufacture a novel body armor from cheap and available materials. In this study, alternative materials were proposed to develop an armor consisting of modified rubber and ebonite, as well as pieces of ceramic from alumina as hexagons shape, Kevlar and Carbon woven, and modern technologies shear thickening fluids. The armor was numerically evaluated using (ANSYS) commercial software using different bullet velocities ranging from (740 to 940) m/s and different numbers of carbon and Kevlar woven soaking shear thickening fluids to reach the best arrangement of layers with the best performance and compare them in the experimental data. The numerical results showed the best performance for plate armor consisting of 23-layers, which were then experimentally tested using a weapon type (AK-47) rifle with bullet 7.62*39 mm. The experimental test showed no complete penetration, with a back deformation of 7.5 mm. When the shock of the double bullet into the plate at the same location showed no complete penetration with a back deformation of 11.3 mm. The experimental data confirmed well with the numerical results and the body armor exhibited superior protective performance and was compatible with standard NIJ Standard-0101.03.
