Abstract : Reinforcing polymer matrices with natural fibres has currently gained momentum among many researchers around the world. This study investigated the effects of alkali treatment on the physicochemical and mechanical performances of Grewia mollis fibre-reinforced waste FARO water bottle composites. The hand layup technique was employed in formulating the composites and their physiochemical and mechanical performances were studied according to ASTM standards. The physiochemical analysis showed that moisture absorption behavior decrease while density properties increase as the concentration of NaOH increases. According to the analysis, the untreated composites absorb more moisture owing to their hydrophilicity nature. The analysis proves that alkali treatment decrease moisture content and increase density properties of the green composites.

Keywords : Alkali Treatment, Characterization, Composite, Fibre, Grewia mollis, Reinforcement, Waste FARO Water Bottles.
