The paper presents the process of enhancing blast resistance of a thin steel plate by reinforcing it by a composite. The composite consisted of five differently orientated layers of high resistant S2/Glass fabric. Such system was subjected to a pressure wave generated by detonation of small TNT charge placed at a certain distance from the plate. Reinforcing the plate with composite layer improved the ballistic and blast wave protection level of the shield. Due to the usage of the composite the overall mass of the entire plate raised only slightly. Proposed solution can be used to improve the characteristics of existing armours by adding extra panels or modifying armours of transport vehicles. For the purpose of the numerical analysis, the Finite Element Method and explicit time integration were used. Calculations were done using LS-Dyna software. Numerical solutions of both steel plate and steel plate with composite are presented and evaluated. Pressure wave of the blast impulse, the physical model of the blast test, Structure of the four composite layer, deformation shape of steel-composite plate (pressure wave in Z-direction, t=1 ms), failure of plies, Huber-Mises-Hencky stress as material effort on plate are presented in the paper.
