In this study, a low-velocity impact test was numerically simulated on Kevlar-29/Epoxy laminates with dimensions of 100 × 100 mm and a thickness of 6 mm, arranged in [0/45/90]₄, [0/30/60/90]₃, and [0/90]₆ orientation sequences using the LS-DYNA software. The impact loading was applied by a 6 mm-diameter impactor with a mass of 15 kg striking the laminates at a velocity of 5.0 m/s. The maximum force values varied depending on the lay-up sequence, and the highest peak force was obtained in the [0/30/60/90] configuration with 45 N. In the energy–time analysis, it was observed that the total energy transferred during the impact was approximately 187.5 J for all three configurations. This impact result suggests using isotropic approach paving rows using different paving methods to maximize energy absorption and increase damage tolerance.
