Abstract

The static, dynamic (like storage modulus and damping behaviour (tanδ)), thermal, hardness and machinability properties of Sansevieria ehrenbergii fiber-reinforced polyester composites were compared with traditionally available materials like plywood, hardboard sheet, paper board and twisted paper according to ASTM standards. The stress-strain curves of the polyester composites and traditionally available materials were analysed, and the results show that the best tensile, flexural and impact properties were achieved with KMnO4 -treated S. ehrenbergii fiber-reinforced polyester composites. The storage modulus of hardboard sheet and KMnO4 -treated S. ehrenbergii fiber-reinforced polyester composite was the highest in the glassy and rubbery regions. The tanδ peak height was minimum and peak width was maximum for hardboard sheet and KMnO4 -treated S. ehrenbergii fiber-reinforced polyester composites. The thermal stability and hardness of the hardboard sheet were the highest compared to S. ehrenbergii fiber-reinforced polymer composites. The delamination factor and water absorption of KMnO4 -treated S. ehrenbergii fiber-reinforced composites and hardboard sheet were lowest compared with the other materials.
