Abstract:In this study, the impact resistance of double-layer concrete panels made of rubberized and steel fiber reinforced concrete subjected to direct fire weapon (11 mm or .44 Magnum bullet size) is investigated. Concrete panels with dimensions of 400x400x50 mm are subjected to impact forces from 11 mm-diameter bullets at a distance of 10 m. Three types of concrete panels are tested: single-layer steel fiber reinforced concrete (SFRC), single-layer crumb rubber concrete (CRC) and double-layer CRC/SFRC. For a double-layer CRC/FRC, the CRC layer of 12.5 mm is added to the front surface to partially replace part of the SFRC panel. It is expected that, with its high elasticity and flexibility, the CRC layer will act as a cushion layer to absorb impact energy from the bullet and reduce the damage to the concrete panel. During the impact event, the acceleration of the plate is measured using an accelerometer. The measured acceleration is then used for calculating the force acting on the plate and also its displacement.
