【 摘 要 】

Natural fibres are gaining attention day by day in industrial applications. The aim of current investigation is to enhance the performance of sisal fibre by its surface modifications. The surface modifications include alkali treatment with varying concentrations (2, 5, 10, 15 & 20 %) and coating of PLA with varying concentrations (2, 4, 6, 8 & 10 %). Treated and untreated sisal fibres were subjected to tensile test and thermo gravimetric analysis (TGA). In addition to this, sisal fibres were characterized by X-ray diffraction (XRD), and its structural morphology was studied by scanning electron microscope (SEM). Moreover, FTIR spectroscope analysis was also carried out to see the removal of hemicelluloses and lignin from sisal fibre by alkali treatment. It was observed that surface modifications had much influenced the performance of sisal fibre. On other hand, PLA coated fibre had a better performance than alkali treated fibre.
