Selection of Materials for Weight Reduction in Sports Cars

Abstract:

The need for studies aiming at the selection of materials for such application is preponderant, be-cause a large increase in the focus on vehicle weight reduction by the automotive industry in recent years. In environmental and commercial terms, this reduction provides lower energy consumption and better vehicle performance, as well as limiting pollutant emissions. The present work has the objective to select the best materials in substitution of the metals and glass used in doors, hood and windows, respectively, of sports cars to decrease the weight/power ratio and consequently improvement of performance. With the aid of Ashby maps simulated through the CES EduPackTM 2018 program, maximizing the limit of tensile strength and minimizing density, it was possible to analyze that carbon fiber composites obtained values of merit index of up to eleven times greater than the value obtained by carbon steels. Already in substitution of the glass, the acrylic obtained a index of merit about three times greater. At the same time, the tensile strength, fracture toughness, density and cost of the possible materials obtained in the previous method were obtained through the Pugh matrix, the exchanges for composites of glass fiber and polycarbonate obtained outstanding responses.
