First and foremost, joining systems with a form closure function enable to pass very high loads into rod- and tube-shaped fibre reinforced structures and achieve high degrees of material utilization for the composite part. This paper demonstrates the theoretical and technological principals for a resource efficient design and production of highly loaded thermoplastic composite profile structures with integrated metallic load introduction elements and a multi scale form closure. The hybrid structures are produced in an integral blow moulding process in which a braided tape-preform is simultaneously consolidated and formed into the metallic load introduction element. These metallic load introduction elements are manufactured in a two-stage process of external and internal hydroforming, after forming simulations have assured process stability for consistent quality.enIntrinsic Hybridthermoplastic composite profile structuresmetallic load introductionmulti scale form closureintegral blow moulding processhydroformingIntrinsic manufacture of hollow thermoplastic composite/metal structuresIntrinsische Fertigung von Thermoplastverbund-Metall-Hohlstrukturenconference paper
