Natural fiber composites are increasingly adopted due to sustainability and lightweight requirements. This work predicts the elastic constants of epoxy-based hybrid laminates reinforced with Pineapple Leaf Fiber (PALF) and Grewia Optiva using Classical Laminate Plate Theory (CLPT). Three stacking sequences—[0/±45/90] (A1), [0/(45)?/–30] (A2), and [0/45/90/30] (A3)—were modeled with PALF content varying from 10 wt.% to 20 wt.% and Grewia Optiva fixed at 20 wt.%. Increasing PALF content enhanced stiffness, with the highest longitudinal modulus (37.32 GPa) obtained for A3. A1 exhibited maximum shear modulus (14.56 GPa), whereas A2 demonstrated the highest Poisson’s ratio (0.31). The results indicate that stacking sequence significantly governs anisotropic behavior, with A3 achieving the most balanced stiffness profile. The study demonstrates that CLPT provides a computationally efficient tool for hybrid natural fiber laminate design. Future work will experimentally validate the predictions and include hygro-thermal considerations.
