TL;DR: In this paper, a new joining technology to produce hybrid structures with continuous fibre reinforced thermoplastics and metallic components is introduced, adapting the concept of classical clinching for thermoplastic composites.

TL;DR: In this article , the state of the art in scientific research concerning mechanical joining and discusses future challenges on the way to versatile mechanical joining processes are discussed, including the creation of intervention possibilities in the process and the understanding and handling of materials that are difficult to join, such as fiber reinforced plastics (FRP) or high-strength metals.

TL;DR: In this paper, the tribo-mechanical properties of different polypropylene (PP) composites were investigated by means of optical microscopy and it was shown that they can be significantly influenced by a suitable reinforcement.

TL;DR: In this paper, two different types of weld inserts were embedded in glass fiber reinforced polypropylene sheets and then welded to steel sheets, and the quality of the joints was analyzed by microsections before and after the welding process.

TL;DR: In this article, the authors proposed a method for connecting thermoplastic fiber composite components by stick-shaped functional elements. But this method requires the functional element to be placed in the initial position of the fiber composite component.
