Ballistic performance evaluation of 3-dimensional orthogonal composite soft armor systems

Bullet penetration resistance is investigated in on use of 3d orthogonal structures for soft armor application which may have positive outcomes with a combination of high-performance yarn in a particular direction. 3d fabric structures have a promising architecture, to develop a soft armor system due to its good mould-ability and its interaction characteristic with the yarns. 3d orthogonal fabric was manufactured on hand-loom; four different variants of the fabrics were woven with the same fabric architecture with different types of yarn in different directions. The research investigated the performance of a single 3d orthogonal fabric of 8 layers and a double 3d orthogonal fabric of a total 16 layers in different variant combinations as per the NIJ standard 101.06 level II-A. The performance of double 3d orthogonal fabric for maximum combinations was optimum to prevent the penetration of the bullet at a velocity as per NIJ std 101.06 level II-A. Besides, the single 3d orthogonal fabric of 8 layers did not perform in preventing the bullet penetration at a higher velocity. The design strategy of combining the 3d fabric variants is implemented to check the ballistic performance of the combined 3d fabric variants when the number of layers of a single 3d fabric is not able to prevent perforation by the projectile. It was observed that 100% kevlar double 3d orthogonal fabric had a lower energy absorption limit due to lesser areal density and lower modulus of the yarns in the fabric structure affecting the energy dissipation of the projectile on the impact. However in comparison to hybrid composite double 3d orthogonal fabric (3dof), with ultra-high molecular weight polyethylene in the z-direction of the second layer of double fabric, improves the energy dissipation capability due to good energy absorption capability of yarn with higher modulus. The back face signature (bfs) values for all the non-penetrated combined double 3d orthogonal fabric combinations were lesser than the standard requirement of 44 mm. The results of the testing show the bfs values were inversely proportional to the areal density of the 3d orthogonal fabrics.
