Natural fibers, pineapple leaf fiber (PALF) and water hyacinth fiber (WHF) are promising reinforcements due to their high tensile strength, availability, and eco-friendly nature. When combined with a polymer matrix, such as epoxy resin(10:1), these fibers enhance the mechanical properties of the composite while maintaining environmental sustainability. The fibers undergo Alkali treatment(7% NaOH for 1 hr at 80°C) to improve interfacial adhesion with the epoxy matrix, ensuring better load transfer and enhanced adhesion between layers.Varying the fiber loading and fiber ratio four samples are made including 2% FL (1:1), 2% FL (4:1), 5% FL (4:1) and 7% FL (4:1).The composite specimens are then subjected to various mechanical tests, including tensile, flexural.5%FL outperforming all of the samples rated MoE (2.436 MPa),UTS (43.932MPa), Elongation 25.355 and Flexural Stress (86.027 MPa) showing balanced mechanical properties.
