Comparative dynamic analysis of carbon, aramid and glass fiber reinforced interply and intraply hybrid composites

Abstract

This study presents a comparative dynamic analysis of hybrid composites, which are suitable for new technological vehicles and possess greater advantages over non-hybrid fiber-reinforced composites. In this context, non-hybrid (NH), interply hybrid (IN) and intraply hybrid (IR) composites are manufactured. In the manufacturing process, NH and IN composites are utilized by using Carbon (C), Aramid (A), and Glass (G) while IR composites are manufactured with Aramid-Carbon (AC), Carbon-Glass (CG), Glass-Aramid (GA). In the manufacturing stage, a variety of layer numbers and fiber orientation angles is taken into consideration to determine the most advantageous structures for vibration characteristics. As there are a great number of productions required because of the parameters of interest, Taguchi production design is used. These composites are manufactured using Vacuum Assisted Resin Transfer Molding (VARTM). In accordance with the relevant standards, density, tensile, and dynamic properties are determined experimentally. Further, numerical models are developed using the ANSYS® software, and modal analysis is conducted. The results of the numerical analysis are compared with the experimental results. Taguchi analyses are performed to determine the most effective manufacturing configurations for the purpose. Consequently, IN and IR composites with similar content are compared to each other and the previous literature. According to the experimental and numerical results, the factors most effective in determining the natural frequency and damping ratio are layer numbers, orientation angles, and fabric types, respectively. The effectiveness of each parameter in the ranking is determined by using Taguchi levels.
