The development of efficient and sustainable armor systems is crucial for protecting bodies vehicles. In this study, epoxy composites reinforced with natural lignocellulosic fibers (NLFs) from carnauba (Copernicia prunifera) were produced 0, 10, 20, 30, 40% fiber volume fractions. Their ballistic performance was evaluated by measuring residual velocity absorbed energy after impact 7.62 mm ammunition, as well their application in a multilayer system (MAS). Scanning electron microscopy (SEM) used to analyze fracture regions, explicit dynamic simulations performed comparison experimental tests. Residual tests indicated limit (VL) between 213 233 m/s (Eabs) 221 264 J, surpassing values reported aramid fabric. All formulations showed indentation depths below the National Institute Justice (NIJ) limit, sample achieving lowest depth (31.2 mm). simulation results correlated data, providing insight into deformation mechanisms during level III event. These findings demonstrate high potential epoxy-based polymer composites, particularly an intermediate layer MAS, offering alternative protection.
