Abstract: When lightweight core materials are mixed with various fiber orientations, hybrid composite laminates frequently exhibit excessive bending deformation, uneven flexural stiffness, and unpredictable deflection patterns. These discrepancies lessen their usefulness in applications like automotive and aerospace structures where reliable mechanical behavior and high stiffness-to-weight performance are crucial. To overcome these constraints and guarantee dependable performance under flexural loading, better material architecture and more precise prediction tools are needed. By strategically adding a Lantor Soric core to increase bending resistance while minimizing weight and optimizing stacking sequences, this study seeks to improve the mechanical stability of hybrid laminates. The method places a strong emphasis on using analytical-numerical validation and careful material design to achieve a balanced structural response. The in-plane and flexural stiffness characteristics are first determined analytically using Classical Lamination Theory (CLT), which offers theoretical insight into laminate behavior. In addition, ANSYS's Finite Element Analysis (FEA) simulates three-point bending conditions to assess stress distribution, deflection patterns, and possible failure regions more accurately. Lastly, the analytical and numerical predictions are verified through experimental three-point flexural testing. This study offers a methodical framework for enhancing hybrid composite laminates through optimized stacking sequences and core integration, driven by the need for more reliable, lightweight, and stable structural solutions.
