Abstract

Modern lightweight constructions are increasingly based on the use of multi-material design such as fibre-reinforced plastics (FRP) combined with metallic material. The technology of screwing is rated, especially for applications where high-strength and permanent joints are required, among the established joining methods. To achieve a high-quality lightweight design, often, profile-intensive constructions are used, with the effect of one-sided accessibility to the joining area. Against this background, flow drill screwing offers an innovative solution for car body construction as well as the assembly for joining this combination of material. Currently, flow drill screwing with a pilot hole in FRP materials is used in the assembly process. To use this technology without a pilot hole and use it economically in the body framework, the auxiliary joining elements have to be optimised. This publication includes the latest research findings in the context of the development and qualification of joining by using flow drilling screws. It focuses on the specific adaptation of the auxiliary joining element with regard to the geometry, the material and the coating systems. With macroscopic and microscopic sections, as well as studies of strength, ultrasound and corrosion, it is possible to assess the quality of new and original FDS joints.
