Abstract:

This research tested Para-aramid (Kevlar) fibrous products of equal specifications (material and density) with respect to the influence of the fabric construction on their bulletproof behaviour. Constant speed and constant deformation energy tests were performed based on the static methods of the Material Test System, in which Armour Piercing Bullets (AP), Full metal Jacket Rifle Bullets (RB), and Fragment Simulating Projectiles (FSP) were applied. Among the samples of Kevlar woven fabrics tested, namely plain, twill, basket, and satin constructions, the plain weave construction demonstrated the best proofing properties against AP and RB, especially during low-speed tests of single-layer materials. In the high-speed FSP bulletproof test of multilayer constructions, 2×2 Basket fabric had the highest ballistic resistance performance, followed by the plain weave construction; the ballistic qualities of both these materials appreciably exceed those of other fibre woven fabrics. Satin fabric exhibited the weakest bulletproof properties in all the tests, apparently because of the weak stability of its construction. The main conclusion that can be drawn from the investigations performed is that in order to withstand a projectile impact, fibre woven fabrics should have a strong enough stability of their construction.
