Abstract
One of the best natural fibers is jute fiber because of its availability, ease of access, and affordability. It has some highly intriguing qualities, including biodegradability and high strength. In this study, the jute composite is designed and fabricated using a 5-layer jute and epoxy resin, utilizing the manual hand lay-up technique. The combination of 52.5% jute and 47.5% of epoxy resin and harder is found optimized to achieve the goals of improving the tensile strength and flexural strength, reducing the weight of the composite, reducing the cost of epoxy resin, and promoting eco-friendliness and sustainability. Tensile testing was performed on a universal machine, while flexural testing was done with a three-point bending test. Experimentally, the composites reinforced with jute and epoxy resin were capable of achieving the required levels of tensile strength (42.91 MPa) and bending strength (69.30 MPa). To validate and visualize specimens, numerical analysis was performed on the ABAQUS simulation software. The numerical simulation utilized ASTM D3039 and ASTM D7264 as the specified requirements for tensile and flexural behavior. For validation, the results of these tensile and flexural tests were then numerically analyzed and compared to the experimental data. Finally, the composite design, fabrication, and optimization can improve mechanical properties, reduce composite weight, lower resin cost, and increase sustainability. The proposed design and composition will be implemented to achieve lightweight properties in various applications such as car components, door handle sheets, bicycle seat backs, and luggage covers.
