Processing relationships of hybrid polymer-metal composites in the injection moulding process

This paper describes the production of polymer-metal-hybrids with different manufacturing parameters during the injection moulding process and their influence on the shear strength. The joining between a polyamide 12 and an aluminium sheet is investigated with variable melting temperatures of the polymer, holding pressure or rather mould temperature of the injection mould. In spite of the variability of the parameters, all process employments established a connection between the parts. It was also shown, that the melting temperature correlates with the shear strength, but the shear strength values are significantly lower than stated in the literature. Finally, the successful joining of the materials to a hybrid demonstrate that such a connection method has the potential to insert in different application fields.
