Abstract
The emerging field in the current research domain is natural fibre reinforced polymer composites as it is having plenty advantages over synthetic fibre composites. The current study is focussed on synthesizing epoxy composite incorporating areca sheath fibre at different fibre fractions from 45% to 65% at the increment of 5%. Investigation revealed optimum fibre fraction to be 55% in case of both raw and 1% sodium hydroxide treated fibre composites. Further, fibers were treated with 0.5%, 1.0%, 1.5%. 2.0% and 2.5% KMnO4 at different exposure time like 5 min and 30 min and composites were fabricated at 55% fibre loading. To confirm the surface modification of fibre, FTIR analysis and X-Ray diffraction analysis were performed. Studies revealed that in both the cases, 0.5% showed maximum tensile and flexural strength. In addition to this, it is also observed that, as the fibre exposure time to KMnO4 increases, the strength of the composites decreases drastically because of damage in fibre surface morphology as showed in FESEM analysis.
