Abstract

Composites have monopolized the automotive, construction, and packaging industry. Their high strength to weight ratio has made them an integral part of numerous engineering applications. In this study biodegradable matrix is combined with areca frond fibres for developing composites for low strength structural applications. Areca frond fibres were extracted and treated with sodium bicarbonate to improve the surface characteristics. Hand lay-up and compression moulding techniques were used to fabricate composites having unidirectional fibre orientation. The specimens prepared were exposed to varied environments, namely, sunlight, OTG oven, steam oven, and hot air oven, for curing and the results were analyzed to best suit the implicated requirements. Scanning electron microscopy was used to observe the changes in surface characteristics of the frond fibres after treatment. Tensile and flexural strength of starch based/areca frond reinforced composites were evaluated according to ASTM standards. Test results revealed that composites cured in a steam oven resulted in improved tensile and flexural strength compared to other curing environments
