Structural capacitors are multifunctional structural materials that provide structural strength and energy storage together and aim to greatly reduce the weight of the system. In this paper, the effect of the dielectric separator materials such as polyvinyl chloride (PVC) and biaxially oriented polypropylene (BOPP), weave structure of carbon fabric and thickness of dielectric material on multifunctional performance of the structural capacitors was investigated. In order to plan experiments, analysis and interpret results, and optimize factors (dielectric separator material, carbon fabric weave type, dielectric material thickness) that affect the multifunctional performance was used Experimental Design (DOE). DOE were carried out using the Taguchi method. Structural capacitor materials were manufactured according to experimental layout based on Taguchi’s L6 orthogonal array and mechanically and electrically tested to evaluate their multifunctional efficiency. In addition, optimal combinations of factor levels were determined and the optimum performance to be obtained with these combinations was calculated by applying Taguchi method. The results show that, higher electrical and mechanical performance is obtained in the structural capacitor used twill-woven fabric. Also, especially PVC film which widely available and low cost a polymer film, can be used as dielectric material in structural capacitors.
