Advancements in natural fiber composites: Market insights, surface modifications, advanced fabrication techniques and applications

Abstract

Natural fiber reinforced polymer composites (NFRPCs) have gained significant attention as sustainable, eco-friendly alternatives to synthetic fiber reinforced composites in various industries, involving construction, automotive, and packaging. This review provides an inclusive analysis of recent advancements in fabrication processes and applications of NFRPCs, highlighting the potential of these materials to tackle environmental challenges and decrease the dependency on fossil-based products. Advances in fabrication methods, such as microwave-assisted curing, infrared curing, autoclave technique, and additive manufacturing, have enabled enhanced fiber-matrix bonding, improved mechanical properties, and increased design flexibility in NFRPCs. Advances in surface treatment and hybridization technique have further expanded the potential applications of NFRPCs by enhancing their durability, moisture resistance, and thermal stability. These improvements make NFRPCs suitable for demanding environments and various applications, from lightweight automobile parts to biodegradable packaging materials. Additionally, the review discusses current challenges, including variability in natural fiber properties and limited durability in harsh conditions, as well as potential solutions to these issues. This review will help in providing insight into the future direction of NFRPCs development and promoting sustainability in various industries.
