Laser direct joining of metal-polymer hybrid connections using a single beam source and processing station
- Laser direct joining of metals and plastics is a promising process for producing strong and reliable joints for lightweight hybrid structures without the need for adhesives, primers or mechanical fasteners. Commonly this process consists of two separate steps using at least two processing stations: the surface of the metal part is textured to achieve an increased surface roughness and improved mechanical interlock between the components. In another step, the thermoplastic components or the matrix of thermoplastic fiber reinforced composites are selectively heated to allow the melt to flow into the prepared metal structures. In this work, a new method is presented that combines highly efficient laser surface texturing of metallic parts and the selective laser heating of the joining zone in a transmission joining process using a single laser beam source running in different operation modes. This enables a very compact and cost-efficient processing station.
