Natural Fibers Reinforced Polymer Composite: Focus on Mechanical, Tribological and Biodegradable Properties

Interest in creating sustainable materials, such as natural fiber-reinforced polymer composites, for various industrial applications has increased due to the depletion of petroleum resources and environmental concerns. Natural fibers are strong and enhance the mechanical strength of polymer matrices through their inherent strength, adhesion to polymers, effective load transfer, damping properties, density reduction, and sustainability benefits. This review study discusses the mechanical properties, tribological properties, and moisture absorption of epoxy, polypropylene, and polyester matrices reinforced with different natural fibers, as well as their applications in various industries. This review also covers mechanical characteristics for natural fiber composites, including dual fiber composites, their impact, tensile and flexural strengths, and hardness from research studies.
