Evaluation of sisal banana epoxy reinforced natural composite

Abstract Natural fibres made from renewable resources, such as banana and sisal, offer enormous promise as reinforcing fibres in polymer composites and a renewable substitute for conventional fibres like glass, carbon, and wood. Banana and sisal fibres are especially prized for their advantageous mechanical qualities, low weight, accessibility, and cost. However, prior research has focused on individual fibres rather than hybrid composites. The mechanical properties of hybrid composites composed of banana and sisal fibre reinforced with an epoxy matrix are investigated in the current work in relation to loading. For gaining balanced stiffness, strength, and ductility, the proportions of fibers were optimized during the process of Compression molding in preparing composite specimens. Tensile, compressive, and impact strength were some of the mechanical properties that were evaluated according to ASTM standards. The results indicated enhanced modulus and tensile strength, highlighting the resistance of the composite to severe mechanical stress. In addition, the excellent performance under a variety of loading conditions was confirmed by compression and impact testing. These findings identify the potential of sisal-banana hybrid composites as green materials, meeting the increasing demand for sustainable, durable, and lightweight alternatives in structural applications. Unlike previous studies that primarily focus on individual natural fibers, this research highlights the synergistic effect of combining sisal and banana fibers, emphasizing the composite’s superior performance and eco-friendly attributes.
