Increasing the energy efficiency in solar vehicles by using composite materials in the front suspension

Abstract

The pursuance of energy efficiency is a constant endeavour in modern mobility. Accordingly, several institutions worldwide have been investing time and resources in developing solar powered vehicles, directing their efforts towards a continual search of technical solutions aiming at attaining the highest energy efficiency levels. This work investigates and compares the mechanical behaviour of a front suspension wheel hub, subjected to its operational forces, when made by three different materials: aluminium, carbon or basalt fiber reinforced composites. Despite of investigating the sole mechanical response of materials, the comparison focuses on the feasibility of applying light and stiff composites in structural parts in order to improve the energy efficiency in vehicles due to weight reduction whilst granting safety.
