【 摘 要 】

In the product manufacturing cycle, the joining of polymers often takes a central position. Vibration welding ischaracterized by short cycle times, high process flexibility and stability as well as by the achievement of high bond strengthswithout using additives. However, the vibration welding process is clearly restricted by a necessary adhesion compatibilityof the joining partners. By means of structuring one joining partner and subsequent filling of the structures by a secondjoining partner, the joining by form-fit using vibration welding enables the combination of adhesion incompatible polymers.Within these investigations, bonds between adhesion incompatible semi-crystalline thermoplastics were generated based onmechanical adhesion. Also semi-crystalline and amorphous polymers could be connected for the first time without any connectingelements, although they conventionally do not show mechanical resilience. The analysis of the thermomechanicalmaterial properties and the resulting multimaterial link enabled the determination of first influences on the resulting formfitconnection caused by the occurring joining zone temperature.
