Abstract

Fiber reinforced plastics (FRP) is classified as one of the main classes of structural materials. Due to its high strength and light weight, it is considered for being used in a large scale of different applications. Particularly, bullet proof vests are widely used in order to protect the soldiers from being targeted in battle fields, however many modifications are being implemented to enhance the bullet resistivity of the vests for achieving more protection. This scientific paper investigates the enhanced properties of Twaron CT 736 when it is being reinforced with epoxy resin and topped with silicon carbide ceramics. The potential application for this kind of enhancement is to produce body armor plates that would resist the penetration of machine gun 7.62 * 39 mm and 7.62 * 51 mm bullets. A ballistic gun and triggering unit for the penetration test were used and the response of the prepared samples was studied. Vacuum bagging technique was adopted to prepare the samples. The final results of this research study show that, in order to stop a machine gun 7.62 * 39 mm normal bullet the plate should contain 30 layers of Twaron CT736 topped with 2 layers of ceramics, while in order to stop a machine gun 7.62 * 51 mm bullet the plate should contain 70 layers of Twaron CT 736 topped with 3 layers of ceramics.
