Current construction methods for soft armour products involve woven and cross-ply laminates. Both methods claim to offer high-energy absorption capability towards projectile impact. Currently, there are less specific data comparing both construction methods. In the cross-ply manufacturing process, the fibers are aligned in one direction, spread into a web and adhered with a resin. Two fiber resin sheets are layered (one in a 0° direction and another in a 90° direction) and fused. Therefore, this study attempted to investigate the effects of different textile designs of aramid fabrics on the ballistic performance, specifically on the energy dissipation and projectile arrest for soft body armour at a 390 m s−1 projectile velocity. It was found that the cross-ply laminated aramid construction exhibited better ballistic performance in terms of higher energy dissipation and minimum layer of projectile arrest upon impact.
