Usually, non-releasable joining techniques such as gluing and welding are used when joining fiber composite components. Alternative force introduction elements, such as e.g. bonded bolts, allow a non-permanent connection, but these have many disadvantages. For example, the setting of an adhesive joint, the curing time of the adhesive as well as the installation space and the application of the bolts is associated with considerable time and effort.
With direct screwing the fasteners (screws) generate a thread when screwed in without cutting. The generated thread results from the forming process when screwing into the polymer material. This system has the advantage of managing without thread cutting. Thus, it is fast, efficient, reproducible and cost-effective.
