The demand for light-weight construction and economic efficiency has led to the development of light-weight construction strategies, i.e., multi-material design, in many areas of industry. Here, the property profiles of the composite partners are utilized synergetically. Plastic-metal hybrid composites possess a large amount of potential in this regard owing to the weight reduction that can be achieved in the composite and the simultaneous enhancement of the mechanical properties. 

Hybrid components have already proven their potential in large structural components for the bodies of cars, and are already employed in series.

A particular difficulty arises in the case of applications where sealing is required between the composite materials. Achieving a firmly bonded connection between the differing materials is a tough challenge, especially since exposure to different temperatures and media can alter the composite properties significantly. This was examined and evaluated in expansive test series.
