Optimization of the Mechanical Properties of Kaolin-Luffa Cylindrica Filled Hybrid Composites Using Taguchi Method

Abstract

Due to the density of low mass and cost are given by most fibers that are natural they have been utilized as a substitute for synthetic fibers. This investigation utilized the Taguchi technique to improve the mechanical properties of unsaturated polyester composites reinforced kaolin-luffa, to examine the process parameters optimized. The development materials that were hybrid composite were set up by hand lay-up. The optimization parameters considered are luffa fiber weight, kaolin filler weight, and kaolin filler size, each at different levels of three. Characterization of Mechanical properties, for example, tensile strength and compressive strength are selected as the objectives of consistency. Taguchi method using an orthogonal array of nine experimental runs based on L9 (33) were performed. The significant effect and data for every parameter were analyzed statistically and optimized using analysis of variance (ANOVA). The investigation was done at a confidence level of 5% significance and it was seen that luffa fiber weight, Kaolin filler weight, and kaolin filler size significantly affect tensile strength and compressive strength. A confirmation test affirmed there were improvements in the S/N ratios for both tensile and compressive strength.
