Reinforced concrete (RC) slabs are prone to severe local damage and punching failure when exposed to low-velocity impacts such as falling debris, rockfalls, or vehicle collisions. This study experimentally and numerically examines the impact performance of RC slabs strengthened with carbon textile-reinforced mortar (TRM) strips. Ten two-way slabs were tested under a constant impact energy of 2.9224 kJ applied by a 198.6 kg drop-weight system. The effects of reinforcement ratio, strip orientation, and strengthening configuration were evaluated through acceleration, displacement, and impact force measurements. carbon textile-reinforced mortar (TRM) strengthening significantly enhanced the slabs’ dynamic performance, reducing maximum and residual displacements by up to 65 % and 70 %, respectively, while improving stiffness and energy absorption. The diagonal double-direction layout achieved the best performance. A finite element model developed in LS-DYNA accurately reproduced the experimental results, with less than 10 % deviation in key responses and consistent damage patterns. The findings demonstrate that carbon textile-reinforced mortar (TRM) strips offer a lightweight, durable, and non-epoxy alternative to conventional FRP systems, providing an effective solution for improving the impact resistance and design reliability of RC slabs.
