Abstract

Abstract

The protection performance and mechanism of explosive reactive armors (ERA) with composite rubber armor as its front or back plate were investigated using experiments and numerical simulation, and the results were examined in comparison with ERA using conventional steel plates of the same area density. The experimental results show that the protection performance of ERA with composite rubber armor as the front or back plates are superior to that of the ERA with steel plates, and the optimal performance is achieved when the rubber composite armor is used as the back plate. The numerical simulation results show that the back plate velocity of the composite rubber armor is 16% higher than that of the ERA with steel plates, the space between the two moving plates of the composite rubber armor and the boundary effect contribute significantly to reducing the length of the escaping shaped charge jet.
