Abstract

This study presents the response of rubber panels subjected to high-velocity impact loading. The mechanical properties and impact performance of rubber panels are altered by the variation in compound ingredients. To investigate the effect of compound ingredients, two types of rubber panels with high (SHA70) and low hardnesses (SHA45) were prepared, and mechanical properties and impact resistance of the panels were measured by high-velocity impact tests in a velocity range of 70–160 m/s. Ballistic limits of about 80 and 94 m/s were obtained for the low- and high-hardness rubbers, respectively, which show that the energy absorption of rubber panels increases as filler loading content increases. In this respect, the finite-element simulation has been performed to investigate the ballistic performance of rubber panels numerically. Rubber panel has been modeled using the LS-DYNA software and employing the experimental results of tensile test to characterize the behavior of panel. The findings show a good agreement between the numerical and experimental data. To study the effect of projectile’s shape, impact resistance of the rubber panels against hemispherical projectiles with different length-to-diameter (L/D) ratios (projectiles with diameters of 8, 10, and 12 mm) was measured and the model was also used. The results demonstrate that energy absorption of the panel increases as the diameter of projectile increases. The energy absorbed by the rubber panels appears in the form of damages that lead to increase their damage zone.
