N2 - This study aims to optimise the construction of soft body armour panels by hybridization. Different ballistic responses of aramid woven fabrics and Ultra High Molecular Weight Polyethylene (UHMWPE) Uni-directional (UD) laminates are investigated for material selection, which is conducted through ballistic test and fractorgaphic observation. According to ballistic test, with increasing of layers in a panel, SEA of Twaron woven panel shows a decrease trend, and Dyneema UD panel exhibits an increasing trend. According to fractorgraphic analysis, Twaron fabric has large transverse deformation under ballistic impact, particularly for back layers. This results in large BFS. For Dyneema UD, thermal damage can result in performance degradation, especially for front layers. Therefore, it is not appropriate for the striking face of a panel. Based on above findings, an optimized hybrid panel is designed by combing Twaron woven fabric before Dyneema UD. Ballistic results show that such hybridization is benefit for energy absorption of the panel and minimize BFS in comparison with other hybrid panel.
