Abstract. The increasing need for environmentally friendly materials encourages research on natural fiber-based composites. This study aims to characterize the physical and mechanical properties of hybrid composites of banana leaf fibers, fiberglass, and epoxy, as an alternative automotive material. The manufacturing process used the hand lay-up method with variations in the volume fraction of banana frond fiber, fiberglass and epoxy (10%; 20%; 70%), (15%; 15%; 70%), (20%; 10%; 70%).And used Experimental Research for Experiment Method. Tests include tensile (ASTM D-3039), impact (ASTM D-5924), and bending (ASTM D-790) tests. Results showed the highest tensile strength at 20% banana leaf fraction reached 38.78 MPa, exceeding the SAE J 1717 standard for car bumper applications. However, increasing the banana leaf fiber decreased the impact strength due to uneven fiber distribution. The highest bending strength was recorded at 69.648 MPa at a balanced fraction of 15% banana fronds and fiberglass. This study indicates the potential of banana leaf fiber hybrid composites as an environmentally friendly alternative material in the automotive industry.
