Mechanical and Physical Behavior of Sisal, Jute, Banana, and Hybrid Natural Fiber Composites: A Review

Abstract

Natural fiber-reinforced composites (NFRCs) have emerged as sustainable alternatives to synthetic composites due to their biodegradability, low cost, and environmental benefits. This review systematically examines the mechanical, thermal, and tribological properties of NFRCs, with particular focus on sisal, jute, banana, and hybrid fiber systems. Key findings demonstrate that surface treatments (alkali, silane, permanganate) significantly enhance fiber-matrix adhesion, improving tensile strength (up to 43%), flexural modulus (up to 22 GPa), and impact resistance. Hybridization with synthetic fibers (glass, carbon) further enhances mechanical performance while mitigating moisture absorption. However, challenges persist in thermal stability (degradation above 200°C) and long-term durability under humid conditions. Advanced manufacturing techniques like resin transfer molding (RTM) and optimized fiber treatments show promise for automotive, construction, and packaging applications. The review identifies critical research gaps in interfacial bonding optimization and scalable processing methods for industrial adoption.
