Hybrid fiber reinforced polymer nanocomposites were prepared from kenaf fiber, coir fiber, polypropylene and montmorillonite nanoclay through hot compression method. The effects of fiber hybridization and montmorillonite on their physical, mechanical and biodegradable properties were subsequently investigated. Before being used, both kenaf and coir fibers were alkali treated with 2% sodium hydroxide solution for the diminution of hydrophilic nature of fiber surfaces and to increase adhesion and compatibility between fiber and polymer matrix. The mechanical properties of composites in terms of the tensile strength and Young's modulus were measured through universal tensile testing machine and found to be improved upon fiber hybridized and montmorillonite incorporated. Fourier transform infrared analysis results indicated new bond formation between hybrid fibers and polymer when montmorillonite was incorporated. The scanning electron microscopy microscopic analysis reveals that montmorillonite strongly improved the adhesion and compatibility between fibers and polymer matrix. Hybridization improved the biodegradability and water absorption characteristics of composites, while MMT addition had the reverse effect on the same properties.
