Effect of fiber content on the physical and mechanical properties of plantain fiber reinforced polystyrene composite

Abstract

ABSTRACT This study focuses on the utilisation of plantain fibres for the development of reinforced polymer composite from waste polystyrene. Varying fibre compositions of 5%, 10%, 15% and 20% were used to fabricate four sets of polystyrene/plantain fibre composites. The composites were evaluated for tensile characteristics (Young’s modulus and elongation at peak), impact and water absorption behaviours as per ASTM standards. It was observed that the young modulus, impact strength and percentage water absorption of the composite increased while elongation at peak decreased with the increase in plantain fibre content. The peak values of Young’s modulus, elongation at break and impact strength obtained were 1144.5423 N/mm2, 1.42 mm, and 78 J/m, respectively. The microstructural analysis done on the specimens revealed the uniformity of the fibres in the polystyrene-based resin matrix. The study has been able to elucidate the potentials of plantain fibres for plastic composite development and is equally applicable in diverse industries.
