 This research work focuses on fibrous composites made from treated and untreated areca sheath, AS, fibres reinforced in polyvinyl chloride, PVC, through injection moulding process. Surface treatments were performed to improve fibre compatibility with the PVC matrix, resulting in increased tensile and flexural strength at early stages of loading, followed by a decline at higher fibre contents. At optimum fibre loading, 18 weight percent, the composite exhibits maximum values for tensile strength, flexural strength, and Young's modulus, making it suitable for automated dashboard and door panel applications. TGA, DMA, biodegradability tests, and SEM were used to analyse the properties of the composites, revealing improved thermal stability, excellent biodegradability, and increased biodegradability with higher fibre content.
