To open composite materials new applications, it is necessary to realize complex geometries, which are appropriate for distribution of forces. The ultrasonic welding technique opens the possibility of joining composites or components of composites or even metallic constructional elements without improper thermal or mechanical load. Beside an enhancement of knowledge in the field of plastic-ultrasonic spot welding and roll seam welding for the first time the metal ultrasonic welding technique is the centre of interest of the research project. At this juncture especially the advantage should be used, that with the metal ultrasonic welding technique bondings between the bearing elements, the glass fibers, can be generated. Further glass fiber fabrics and clutches should be joined with ultrasonic welding to mechanical claimable complex geometries. The integration of metallic construction elements before the impregnation and consolidation of fabrics resp. clutches is an further technical interesting production step, because in this way metallic construction elements can be embedded directly into the composite. Further important steps are the investigation of mechanical properties as tensile sheer, sheer and peel strength, microscopic, thermometric and analytical evaluation of the joining zone to characterize the bonding mechanisms. With the realization of the research project a considerable enhancement of knowledge in the field of producing methods of glass-fiber composites are expected.
