Nowadays, natural fibers as reinforcement for composites are gaining a lot of attention. Ensete Ventricosum is one of the appropriate plants from which the natural fiber is obtained. Three wheelers which are commonly known as Bajaj, are the major taxi services in most of Ethiopian towns. The structural roof of this Vehicle is manufactured from synthetic polystyrene cloth sheath which is easily bent, not robust enough and non-degradable after service time. So, the aim of this study was to characterize mechanical and physical properties of Ensete Ventricosum fiber reinforced Polyester resin composite material for three wheeler Bajaj vehicles roof. The fiber which is the byproduct of food preparation process from ensete plant was collected from Hossaena town and treated by 5% NaOH solution for 4-hour duration for fiber‘s surface enhancement. Then, the five distinct composite samples were manufactured from this treated fiber by using plain woven, nonwoven bidirectional and mixture of plain woven and nonwoven bidirectional type of fiber. Also, the fiber was oriented at different ply angle of orientations such as and . The volume fraction of Ensete fiber to polyester resin used for this study was 20%/80% and the hand layup technique of sample fabrication was utilized. Finally, both mechanical performance such as tensile strength, flexural strength, impact strength and water absorption of the five distinct samples were tested. The result of the test revealed that the plain woven ensete ventricosum fiber reinforced polyester resin composite sample with fiber angle of orientation at has the highest tensile strength of 175.3 MPa and highest flexural strength of 336 MPa. And also, the optimum water absorption was obtained as the Composite sample was fabricated from plain woven oriented at . Generally, the three wheeler Bajaj roof was manufactured from composite materials by using plain woven ensete fiber reinforced polyester resin that was oriented at .
