Experimental Study on Penetration of Small Caliber Ammunition into Different Multilayer Compact Armors

Abstract

Nowadays Lightweight armor is very important and used in many applications. Through this study, Penetration behavior was studied through two different types of armors. The first one produced was lightweight composite armor with reducing the number of layers to less than 25 layers of Kevlar using polyurethane rubber resin with high impact and tenacity properties, while the second produced type was a multilayer armor with less than 25 layers of aramid but without using resin Line-x coating in the back. The hand lay-up technique was used for the first type, while the second type was produced by stitching the back layers. Samples were tested for their properties and its ability to defeat 9 mm bullets in protection level IIIA according to NIJ standards. Afterwards the behavior of the small caliber into the two types by the post firing examination tests were studied, where the results resulted in (no penetration) for the two types and complete protection with very lightweight and very thin armor with different reaction of trauma.

Assessment of the mechanical properties of different textile materials used for outer shell of bulletproof vest: woven fabrics for military applications

“…Textile-based products with improved properties and multiple advantages over textile-based products are becoming increasingly popular (Koruyucu and Durmaz, 2018). Polyurethane is one of the most commonly used synthetic polymers for the coating of textile materials because of its excellent durability, stiffness, tensile and tear strength and high abrasion resistance (Kovacevic et al , 2010; Matković and Skenderi, 2013; Cireli et al , 2007; Abo El Amaim et al , 2017). The purpose of this study is to investigate the performance of four different textile materials with various specifications and study its performance efficiency as an outer shell of the bulletproof vest.…”
