Mechanical joining and adhesive bonding - joining processes with new challenges to materials testing

摘要

This contribution highlights new material combinations in the automotive industry to demonstrate the mutual dependence of joining processes and their implications for the geometric shaping of fasteners in the combined shaping and adhesive bonding joining process. The mechanical properties of joints produced by combined and elementary methods are compared taking into consideration quasi static, oscillating and impact-type loads, and ageing characteristics. The results demonstrate that the combination of mechanical and adhesive bonding methods produces joints of high technological quality which can be implemented in optimised light-weight construction. General information is provided on the use of low-heat hybrid joining technology for project planning of this type of connections in industrial practice.
