“…The experiments showed that a combination of 31 wt% banana fibre and 4 wt% tamarind seed particles exhibited the highest tensile strength (27.73 MPa), flexural strength (46 MPa), and impact strength (12.8 kJ/m2) of the four samples with varying tamarind content due to better interfacial adhesion among the fibre, matrix, and filler surface. However, water absorption intake of composite specimens containing 0, 2, 4, and 6 wt% of tamarind seed particles was approximately 43, 23, 27, and 31 percent which shows that the appropriate amount of tamarind seed powder increased absorption [30]. Tensile tests revealed maximum extreme tensile strength of 9.66 MPa that was achieved with the 25 wt% coconut fibre sample.…”

Natural fibres are highly desirable in composites as they are renewable, biodegradable, and cost-effective. They are also abundant in nature with many different types available all over the world. However, despite their advantages, key challenges such as poor fibre-matrix interfacial bonding and moisture absorption limit their widespread adoption in more sophisticated applications. This article provides an overview of natural fibres, including classifications, types, properties, advantages, and disadvantages, with a subsequent review of recent studies, focusing on fibre-matrix selection, treatment methods, and characterization to better understand the current situation. It is apparent from these studies that water absorption is a significant challenge due to the inherent hydrophilic nature of natural fibres as even after treatments like mercerization and silane were applied, substantial amounts of absorption were observed. The effects of powder fillers also vary, with beneficial effects up to a certain proportion, beyond which they became detrimental.
