Summary
Understanding the basic properties of natural fibers is important to determine the optimal intended uses for instance as high-quality bio-composite raw material. This review describes the characteristics, and potential uses of some natural fibers in order to improve their sustainability and economic values. The natural fibers have low density and high strength to weight ratio and reduction make them potential as light weight composite and reinforcement materials. The microstructure and chemical compositions of fibers affect the mechanical properties with the fiber cross-sectional area is the most variable influencing the fiber strength. Natural fibers are easy to absorb water due to the presence of hemicellulose that give hydrophilic properties make them less compatible in the interaction
Regional applicability
This is a materials science review without geographic specificity. The findings on natural fibre properties and processing are globally applicable, though the sourcing and sustainability benefits would be particularly relevant to agricultural regions in the UK and Europe with potential for fibre crop cultivation or agricultural residue valorisation.
Key measures
Fibre density, strength-to-weight ratio, cellulose content, crystallinity, lignin content, water absorption, mechanical properties, fibre cross-sectional area
Outcomes reported
The review synthesises knowledge on the physical, chemical and mechanical properties of natural fibres and their suitability as reinforcement materials in bio-composites. It identifies key factors affecting fibre quality including cellulose content, crystallinity, lignin composition, and environmental/storage conditions.
