Sustainable banana fiber has become potential alternative reinforcement materials instead of synthetic fibers for the development of the polymer composites. These natural fiber-reinforced polymer composites can be utilized for numerous applications. The current study aims to fabricate the epoxy/banana fiber composites under varying fraction of banana fibers. Compression molding process was employed to fabricate the composites since it is frequently used for production of large-scale composite parts like automotive components. Various weight percentages of banana fiber (50%, 60%, 70%, and 80% by weight) and epoxy (50%, 40%, 30%, and 20% by weight) were utilized for the development of the composites. Results revealed that the combination of the epoxy (40 wt. %)/banana fiber (60%) has the higher tensile strength of 22.67 MPa, flexural strength of 39.56 MPa, impact strength of 2.97 kJ/m2, and Barcol hardness of 35.24 among the various combinations of the epoxy and banana fiber composites. This work highlights the viability of sustainable materials within the materials engineering field, promoting the development of eco-friendly alternatives in composite fabrication.
