Hybrid technological approaches, either joining different types of materials or combining different material processing technologies, are of topical interest in industry. Such approaches improve component properties, allow light wave construction and facilitate a resource efficient production. In particular, hybrid metal – polymer composites attract considerable interest for, e.g. lightweight applications. The quality of hybrid metal – polymer composites unavoidably depends on the interlocking joining area between the two involved bonding surfaces.

Typically, the metal surface is structured by a laser-optical or mechanical treatment before the polymer is thermally joined to it in order to improve the adhesive forces between both materials. Implementation of additive manufacturing can redundantise this additional process step, as appropriate surface structures are specifically built on the defined joining area.

The aim of this research project is the development and evaluation of surface structures fabricated by additive manufacturing, which enhance the stability of the subsequent thermal joining process relative to a classical subtractive surface treatment.
