Particle swarm optimization of tensile strength on treated Bermuda grass Fiber as reinforcement in polyester composites

Abstract

The tensile strength of chemical treated Bermuda grass fiber reinforced polymer composites were assessed in this work. This investigation enhanced the binding nature of the Bermuda grass fiber through NaOH treatment, which is used as reinforcement in composite material. The difficult of reduced compatibility among fiber and the resin matrix has been diluted by creating rough surface of Bermuda grass fiber through sodium hydroxide (NaOH) solution. The result of surface modification parameters on the tensile strength of Bermuda grass-polyester composite was analyzed and found that it influence majorly in the tensile strength of composites. The value of 19 MPa, was found as maximum tensile strength through NaOH alkali treatment. The Response Surface Methodology (RSM) approach was used to model the mechanical strength of treated Bermuda Grass-polyester composites. The mathematical equation formed using RSM and the Particle Swarm Optimization (PSO) technique is used to find the better mechanical properties.
