Prozess-Struktur-Eigenschafts-Beziehungen hybrider Polymer-Metall-Verbundstrukturen aus dem Spritzgießprozess

The combination of metal and plastic parts in form of hybrid components is increasingly establishing itself in the area of lightweight construction. The components are connected by an additional process step after the production of the single parts. The target is to implement a single-stage process which can be mass produced and enables reproducible properties. Plastic parts are produced industrially by injection moulding, which is why this process is ideal for implementing of an injection moulding hybrid concept. The resulting composite properties are significantly influenced by the manufacturing parameters. In this work, suitable metal-plastic combinations, adhesion promoters and injection moulding tools for the production of hybrids in the injection moulding process were first identified. To define the technical process limits, the materials were produced in several test series with different manufacturing parameters. The interfaces of the hybrids were tested with mechanical test methods and analysed with optical methods such as microscopy. The resulting composite strengths had large scatter ranges but an improvement of the adhesion was observed with an increase in temperature and pressure parameters
