Lightweight Design is becoming increasingly important for automotive engineering. Fiber reinforced plastics have a wide range of advantages compared to metal based materials, in addition to the weight-saving aspect. In this study, a wheel of carbon fiber reinforced plastics with an integrated electric motor was developed. The main focus of the development was to achieve the optimum of lightweight potential considering structural durability. During the realization, the technical challenges of multifunctional design were considered in the whole product life cycle. Finally, an outlook regarding the validation of structural durability and system reliability of composite safety components is given, in general. In this project a prototype composite wheel with integrated hub motor was developed. The objective to achieve an optimized lightweight design was reached successfully. The special material properties were used to develop a multifunctional component with reduced weight, increased structural damping and improved damage tolerance. For composite wheels, the same safety level as metallic wheels has to be verified. In this connection, the same operating conditions must be considered. At present there are no definitive test guidelines for the approval of fiber reinforced wheels on German roads but work on this is currently in progress. Another challenge is the manufacturing in large quantities. To produce large numbers of carbon wheels cost-efficiently, the usage of alternative processes, e.g. pressing method, is needed. However, with a shorter fiber length the possible weight reduction is not fully exploited. Therefore, the aim is to find an acceptable compromise between weight reduction and manufacturing costs.
