Natural Fibers and its Polymer Composites: A Comprehensive Review from 2000 to 2024

The use of natural fiber-reinforced polymer matrix composites in transportation diligences is be-coming inevitable because of the material’s lightweight, good environmental impact, antibacterial, not producing any harmful chemicals during production, low cost, and excellent characteristics. These fibres have a high hydrophilic nature, shrink-age and have poor dimensional stability and less durability which are the main drawbacks of using them. The interfacial connection between the matrix and fibre has a significant impact on the mechanical characteristics of composites. The mechanical qualities of composites are enhanced by the use of various chemical treatments that enhance the bond between the matrix and fibres. Additionally, a tiny amount of both natural and manufactured fillers, known as additives, boosts the composites’ overall mechanical strength. High strength with low-weight compounds yields different manufacturing methods of composites employed in industries based on the requirements and their applications. The aerospace and automotive industries are exploring the use of composites as a possible alternative to conventional high-density materials. The objective is to reduce vehicle weight while enhancing vehicle performance. Natural fibre-reinforced composites, their many chemical treatments, manufacturing methods, additives, and their many uses are all covered extensively in this review article.
