    Defence can play a paramount role in military organization thus designing light weight armour capable of protecting target from lethal damage is important. While the traditional armour plated use high hardness steel but in recent development of advanced ceramics with low density and high strength properties have opened new door of possibilities in the field. The presented paper bring outs a study regarding protection efficiency of superposed sandwiched panel with metal matrix interface and honeycomb structures against ballistic impacts is performed. The authors have developed a composite armour plate with non-ricochet properties capable of taking resisting multiple projectiles, using ceramics Honey-comb structure tile glued together encased within metal matrix. Paper discusses experimental data, geometry of the experimental setup, modelling (meshing and initial conditions). Numerical analysis has been done on different metals, ceramics and polymers and the best among them are selected. The stacking sequence of the selected materials is developed using crashworthy design concepts. Design parameters for optimized sandwiched panel are provided and superposed sandwiched panel responses with metal matrix interface and honeycomb structures are assessed.
