The body armour sector is increasingly focusing on ultra-high-molecular-weight polyethylene (UHMWPE) fibres due to their strength-to-weight ratio of around 40% higher than aramid fibers. However, UHMWPE fibres have drawbacks in ballistic protection systems, such as low creep resistance, low melting temperature, and poor fibre adherence. The proposed solution involves using surface-modified graphene oxide to improve the stiffness and thermal resistance of polyurethane resin and modify the surface characteristics of UHMWPE fibre. The treated UHMWPE fibre is then stacked with reinforced polyurethane resin to create a hybrid laminated composite panel. The composite panels will be characterized and investigated against impact velocities between 300-500 m or s to assess energy absorption capabilities. Post-impact failure analysis will be conducted using optical techniques to understand the in-depth damage mechanism of flat composite panels. A 3-dimensional finite element framework will be developed to predict the detailed failure mechanism against high-velocity impact. The validated computer model will be used to design curved composite panels for personal and vehicle armor.
