Manufacturing of Hybrid Solid Components by Tailored Forming

Abstract

Constantly increasing requirements for technical components considering strength, functional integration, lightweight construction as well as saving resources lead to the demand for high-performance components with locally adapted properties. In order to meet these requirements, the combination of different materials within one component is of major importance. Within the Collaborative Research Centre (CRC) 1153, innovative process chains are being developed to realise a new class of hybrid solid components. In contrast to existing manufacturing processes of hybrid solid components, where the joining process takes place during forming or at the end of the process chain, tailored semi-finished workpieces are used, which are joined before the forming process. This results in a geometric and thermomechanical influence on the joining zone during the forming process which cannot be created by conventional joining techniques. In the scope of this work the Tailored Forming approach is defined and an overview of the applied joining, forming and finishing steps is given as well as a short summary of the accompanying design and evaluation methods.
