This study presents a detailed numerical investigation of hybrid composite armors as a cost-effective and lightweight solution for ballistic protection. With increasing the demand of protective systems that ensure high mobility with light weight and cost-effective armor without compromising safety. Traditional steel armor has already proven to be a reliable protection system but the main problem is its mobility. To address this issue, the work focuses on composite material as armor. In this study steel, Kevlar 29 and cement-fiber were arranged in different stacking sequences and thicknesses and simulated using ANSYS Explicit Dynamics. A total of eight samples were designed and subjected to projectile impacts to analyze their deformation responses. This result demonstrates that both material type and layering sequence can influence the result. Also play critical roles in determining the ballistic resistance of the composite armor. Steel ensured superior stiffness and minimal deformation while Kevlar displayed higher flexibility and energy absorption but with greater displacement. Cement fiber showed moderate resistance. Importantly in the hybrid configurations, if steel is placed at the end part of the armor it significantly improves overall performance by reducing back-faced deformation. The model was validated against published data with a minimal error margin, to ensure the accuracy and reliability of this simulation process. The study underscores the importance of numerical modeling in optimizing armor design by reducing experimental costs and accelerating the development of advanced protective systems.
