This study investigates the mechanical properties and characteristics of bio-degradable waste banana and neem fiber reinforced epoxy hybrid composites. The composites were prepared with different blending ratios of banana (BF) and neem (NF) fibers. The effects of chemical treatments on the tensile strength and moisture absorption performance of the composites were studied according to ASTM standards. The results showed that the silane-treated BF/NF (3:1) composite had a density of 1.3 ± 0.11 g/cc, a tensile strength of 72.45 ± 1.1 MPa, and a moisture absorption resistance of 43.78%. The tensile strength performance of the silane-treated composite under dry conditions was 56.19 ± 1.1 MPa. The study also examined the mechanical and wear behavior of the composites, and the results showed improved mechanical and tribological properties. The composites were fabricated using hand layup technique and conventional methods. The results indicated that the use of chemically treated banana fibers improved the mechanical strength and water absorption resistance of the composites. The study highlights the potential of using bio-degradable agricultural waste as a sustainable alternative for reinforcing materials in various applications. The results suggest that the silane-treated BF/NF (3:1) composite is a promising candidate for automotive roof frame applications due to its high tensile strength and moisture absorption resistance. The study also emphasizes the importance of chemical treatments in enhancing the mechanical properties of natural fiber composites. The findings contribute to the development of sustainable and eco-friendly composite materials for various engineering applications.This study investigates the mechanical properties and characteristics of bio-degradable waste banana and neem fiber reinforced epoxy hybrid composites.
