Abstract

Composite Ballistic body armor materials has become a better body armor protection as compared to traditional steel body armor in terms of its reduction in weight and an improvement in ballistic resistance[1,2]. However, the complex response of composite materials coupled with high costs and limited amount of data from ballistic testing has lead to modeling and simulation of ballistic body armor with different grade of material becomes the best option to optimize and design the composite body armor with less weight and affordable cost. The long term goal of this research is to develop domestic knowledge, model and simulate capability of composite armors with less cost and weight. As a research methodology there was modeling and simulation by Solid work 2012 and Abaqus 6.10software were used to model and simulate the composite bullet resistant body armor respectively. The material used for modeling of composite body armor was Kevlar-29 fiber and polyester resin. The simulation result for 20layers (10mm thick) of woven Kevlar-29 fiber with polyester resin as a matrix shows that there is no penetration through the modeled composite body armor panel by a projectile of 7.62x39mm bullet impact load at 10 and 50meters and the weight of modeled composite body armor was 0.9kg. There is also bullet resistant body armor that modeled as integral armor from16layers and 5mmthick sheet metal steel and it weighs about 1.5Kg. These results were validated against published data and good correlation was observed. By considering the current thickness and weight of modeled and simulated bullet resistant composite body armor there is a recommendation thrown to any researcher to reduce the weight in terms of thickness in any available technique.
