The Effects of Regressors on Tensile Strength Responses of RHUS Fiber Reinforced Thermoset Composites
Publication Date : 08/02/2021
Due to environmental concern on synthetic fibers (such as glass, carbon, ceramic fibers, etc.) natural fibers such as rhus, hemp, jute, kenaf, etc. are widely used. In this research work, rhus fiber reinforced polyester matrix composites have been developed by hot compression moulding technique with varying process parameters, such as fiber condition (untreated and alkali treated), fiber sizes (1, 2 and 4 mm) and percentages (5%, 10% and 15% by weight). The developed rhus fiber reinforced composites were then characterized by tensile test, and the effects of regressors on tensile strength responses analyzed. The results show that tensile strength increases with increase in the fiber size and fiber percentage; however, after a certain size and percentage, the tensile strength decreases again. Compared to untreated fiber, no significant change in tensile strength has been observed for treated rhus fiber reinforcement.
