Abstract : Bullet proof vests or armours are the protective devices used to protect the individual from bullets or high speed projectiles. A variety of such vests is available currently and they offer bullet resistant for a particular level or grade of threat. The material used to produce the bullet proof armour offers protection. The requisite properties and various strength levels are obtained by different types of materials that can be used to for production. In addition to the contribution of the material in imparting strength, the quantity of material used also is an important factor for strength. Vests with least weight and thickness form the current trend in the market. The main focus of this research work was to develop bullet proof armour using a sandwich of epoxy composite and a ceramic backing material. When a bullet fired from handgun strikes the bullet proof armour, it is caught in a “web” of very strong reinforcing fibers. The impact energy transmitted to the bullet proof vest from the bullet causing the deformation of the bulle is absorbed and dispersed by these fibers. Most anti-ballistic materials, like bullet proof vests are made of Kevlar fibers, Twaron fibres, Dyneema fibres etc. in multiple layers. Kevlar fibers are used in the presented work. The effectiveness of the panels would be determined by ballistic testing for penetration.
