Within the Transregional Collaborative Research Centre PT-PIESA "High-Volume Production-Compatible Production Technologies for Lightmetal and Fiber Composite-Based Components with Integrated Piezo Sensors and Actuators" effective technologies for the production of active components are investigated. One concept is the direct integration of piezo material as fibers or rods in sheet metal like for instance aluminum sheets. This paper deals with the production step of the joining process. Based on a finite element simulation different dimensional layouts are experimentally investigated. The results show, that with an appropriate fill ratio a force-locked connection between piezo material and carrier material can be achieved.
