Development of a Mechanical Technology for Joining Sandwich Elements

Abstract

Wide spread use of sandwich structures is still inhibited by the lack of a consistent joining technology one which is easy to work with, quantifiable and not dependent on special knowledge about manufacturing processes. A mechanical technology for joining sandwiches as developed in this article shall achieve these goals. The developing process follows the design methodology according to Pahl et al. [1]. The resulting systematic approach to the problem facilitated the generation of a complete solution field. This approach led to 18 promising concepts of 783 possible original solutions. Prototypes of those concepts showed that a reliable mechanical technology for joining sandwich elements is feasible.
