 Hybrid composites made of neem and banana fibers with epoxy resin were fabricated using hand-layup method, and their tensile strength was investigated under different fiber loading, chemical treatment, and moisture absorption conditions. The B,N, for colon 1, composite had the highest tensile strength of 52 MPa due to the presence of more banana fiber with high strength, while the B,N, 1 colon 4, composite had the lowest tensile strength of 47 MPa due to the presence of more neem fiber with low strength. Chemical treatment improved the tensile strength significantly by removing impurities and lignin from the fiber surface. Silane-treated composites showed greater tensile strength than alkali-treated and untreated composites, with the B,N, for colon 1, composite exhibiting a 17.5% and 42.3% improvement in tensile strength compared to the alkali-treated and untreated composites respectively. Moisture absorption reduced the tensile strength of all composites, with the B,N, 1 colon 4, B,N, 1 colon 1, and B,N, for colon 1, composites showing a 14.7% 10% and 5.8% reduction in tensile strength respectively compared to dry samples.
