Mechanical and water absorption behaviour of banana/sisal reinforced hybrid composites

The tensile, flexural, impact and water absorption tests were carried out using banana/epoxy composite material. Initially, optimum fiber length and weight percentage were determined. To improve the mechanical properties, banana fiber was hybridised with sisal fiber. This study showed that addition of sisal fiber in banana/epoxy composites of up to 50% by weight results in increasing the mechanical properties and decreasing the moisture absorption property. Morphological analysis was carried out to observe fracture behaviour and fiber pull-out of the samples using scanning electron microscope.

► It explores the utilization of waste banana fiber.
► Improving the mechanical property by hybridization.
► Results show its usefulness to low cost application.
