Abstract

Composites materials in the defense, marine, aviation, and automotive industries are growing due to their excellent mechanical properties and lower density compared with metallic materials. In the automotive industry, the reduction of weight and reduction of fuel consumption is essential to increase the vehicle's performance. Most automotive industries manufacture automotive wheels from metallic materials. The present work is a carbon-reinforced composite material, and structural steel for lightweight automotive wheel application was compared and analyzed. The selected vehicle's actual model was modeled in SOLIDWORK 17 and the analysis in ANSYS 18.1, and the result was obtained. In the numerical analysis, using a laminated carbon/epoxy (fiber reinforced) composite material wheel rather than the structural steel wheel reduces the equivalent (Von-Mises) stress by 31.5%. Total deformation by 15.5%, compared with the structural steel wheel, using reinforced carbon epoxy automotive wheel has 80.4% weight reduction. This unsprung weight of the vehicle decreases, and performance increases.
