Natural fiber composites provide eco-friendly alternatives to synthetic fiber composites but suffer from lower strength and thermal resistance. Hybrid reinforcement using jute–sisal fibers combined with nano-fillers significantly improves mechanical, thermal, and microstructural performance. This review analyzes fabrication techniques, mechanical/thermal behavior, microstructural evolution, and industrial applicability of hybrid jute–sisal nano-composites,
Introduction
Natural fiber composites, particularly jute–sisal hybrids, are gaining attention for their biodegradability, low cost, and lightweight nature. Individually, jute offers high tensile strength and stiffness, while sisal provides toughness and impact resistance. Hybridization of these fibers produces composites with a synergistic balance of mechanical properties, further enhanced by nano-fillers (e.g., nano-clay, SiO?, CNTs, graphene), which improve interfacial bonding, load transfer, thermal stability, and resistance to crack propagation.
Fabrication methods include hand lay-up, compression molding, vacuum bagging, and resin transfer molding, with uniform nano-filler dispersion being critical. The resulting composites show significant improvements in tensile, flexural, impact, and hardness properties, as well as thermal stability, heat deflection temperature, and polymer crystallinity. Overall, hybrid jute–sisal–nano composites provide eco-friendly, durable, and thermally stable alternatives to synthetic fiber composites, suitable for load-bearing, high-performance, and long-life applications.
