Investigation of electrical resistance on coir fiber reinforced P-polyvinyl chloride composites

Abstract Current power electronics instruments like switches, cables, transformers and good electrical insulating materials are gaining consideration for their compact and environmental design. A plasticized polyvinyl chloride/coir fiber-based polymer composite, displaying good electrical resistance, is suggested to meet these objectives. Coir fiber is chosen as it gives powered strength and has fewer lumens than other fillers. Plasticized polyvinyl chloride is strengthened using coir fiber to create a insulating polymer composites. The design of experiments (DOE) method is used to create various samples with 2/4/6 wt.% of fiber content, 75/150/225 μm of fiber size and triethoxy (ethyl) silane (1)/sodium hydroxide (2)/potassium hydroxide (3) of chemical treatments using the response surface methodology through Box–Behnken design. Further, analysis of variance (ANOVA) is carried out using MINITAB statistical software to achieve optimum parameter levels through the regression equation. Additionally, the comparison of experimental and optimized findings leads to error analysis. A combination of 2 wt.% of coir fiber, 208.33 μm of coir fiber size and Triethoxy(ethyl) silane Treatment produces a composite with high resistance of 274.47 Giga-ohms, which is significant for good insulating purpose.
