The use of radiation-cured adhesives on adhesive stud assembly process

摘要

The use of adhesive studs is gaining an importance as a method for assembly and mounting options as part of the trend towards multi-material design. For the efficient implementation of this technique, it is crucial that a reproducible and-above all-fast manufacturing process can be guaranteed. The use of radiation-cured adhesive provides a good solution. In context of a research project, which was performed at the Laboratory of Material and Joining Technology at the University of Paderborn, adhesives studs are characterized in terms of application-specific requirements, e.g., behavior under different loads or the combination with environmental influences or process time. The results that were achieved through the research show the potential of adhesive studs for assembly applications. The mechanical properties meet the requirements of a wide range of mounting options. Total cycle times under 10 seconds provide the basis for adhesive studs to be a real competitor to the established mechanical and thermal joining technologies.
