Outline
The particle velocity of the rubber composite armor and the mechanism of the armor interfering with the shaped charge jet were studied by analyzing the wave propagation rules in the armor. The fracture model of shaped charge jet affected by the rubber composite armor was put forward based on the jet fracture model in the air. The effect of the armor thickness on the jet fracture was also analyzed. The theoretical conclusion was proved by the X-ray and DOP (Depth of Penetration) experiments of Ø56 mm standard shaped charge jet penetrating the rubber composite armor with difference rubber thickness at the angle of 68°. The results show that the rubber composite armor can disturb the shaped charge jet effectively and the protection capability reduces with the increasing of the natural rubber thickness while the thickness satisfied the structure effect.
