With increased concern about reducing the carbon footprint on the earth and promoting sustainability, research on economic bio-products has gained significant attention in recent years. Natural fibers and their derivatives, such as composite materials have gained considerable interest due to their low cost, sustainability, biodegradability, mostly acceptable mechanical properties, and availability. It is vital to recognize the interactive characteristics of cellulosic natural fibers with matrix materials to effectively utilize such fibers as the reinforcement phase in forming composite materials. However, the characterization of these fibers and their composites is complex due to their natural origin and lack of homogeneity. An effort is made here to provide an overview of the current state of knowledge on the characterization, and the methods for characterizing the morphology, composition, thermal and mechanical properties of natural fibers and their composites. The review of characterizations involves Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM), X-ray Diffraction (XRD), Differential scanning calorimetry (DSC), Thermogravimetric analysis (TGA), Tensile, Flexural and impact behaviour of the composites. This review presents a comprehensive understanding of the key characteristics of cellulosic fibers and their composites, serving as a valuable resource for researchers, engineers, and practitioners involved in developing and utilizing eco-friendly materials.
