“…The need for complex design and dimensioning strategies led to the refinement of material models which were subsequently used to successfully dimension highly integrated structures consisting of GF‐PP hybrid yarn‐based composites. Importantly, it was possible to not only demonstrate the applicability of the fundamental research carried out to high‐volume, future‐oriented sectors such as electric mobility, but also integrate the research results into the development of initial application‐oriented components …”

“…This material combination was specifically chosen due to its favorable properties, comparatively low price and in particular the good availability of both the individual components and the commercially available yarns used for benchmarking purposes. Reinforced thermoplastics offer a range of promising benefits to design and manufacturing processes due to the variety of thermoplastic materials available (e.g., with continuous, long, or short fiber reinforcement) as well as the potential combination thereof with various different highly efficient processing chains . Their relatively low procurement costs and good mechanical properties make thermoplastic composites predestined for high‐volume sectors such as the automotive industry, mechanical engineering, and shipbuilding.…”

Future mobility applications are characterized by a high level of resource efficiency due to the application of novel lightweight materials and function-integrating, multi-material design concepts. Textile thermoplastic composites in particular pave the way for lightweight components characterized by highly specific mechanical properties and efficient production processes. This essay presents the strategy pursued by the Collaborative Research Centre SFB 639 "Textile-reinforced composite components for function-integrating multi-material design in complex lightweight applications", a concept for the holistic analysis of complex process chains for hybrid yarn textile thermoplastic (HYTT) composites and the idea behind the innovative FiF electric mobility technology demonstrator vehicle.

“…Hybrid structures made of textile reinforced thermoplastics and metallic components have proven to be very efficient due to their high-volume manufacturing ability and their adjustable high-level mechanical properties [1,2]. To fully exploit the specific structural and functional properties of the different materials, it is necessary to provide specific joining technologies.…”

In order to take advantage of the specific structural and functional properties inside a multi-material assembly, it is necessary to provide adapted joining technologies. Therefore, the new joining technology "thermoclinching" was developed to join endless fiber reinforced thermoplastic composites and metallic joining partners. Previous experimental and numerical studies demonstrated the potential of the novel joining technology. In experimental and numerical studies essential geometrical and material parameters influencing the forming behavior are identified and evaluated. Thereby, the inline-thermoclinching technology is developed by integrating the pre-processed steps of cutting and heating into the actual joining process. For structural analysis of the joining zone as well as for quality analysis and validation of the process simulations computer tomography (CT) is used. Furthermore, experimental characterizations of the failure behavior of thermoclinched joints and the development of simulation models as well as strategies for numerical strength analyses are carried out.

Vor diesem Hintergrund wurde die Thermoclinch-Technologie entwickelt, um endlosfaserverstärkte thermoplastische Verbundwerkstoffe und metallische Fügepartner zu verbinden. Erste Studien verdeutlichen das Potenzial der neuartigen Fügetechnologie; jedoch sind detailliertere Untersuchungen zur Bereitstellung eines robusten Thermoclinch-Prozesses erforderlich. In systematischen experimentellen und numerischen Parameterstudien werden wesentliche Einflussgrößen auf das Umformverhalten identifiziert und bewertet. Dabei wird die Prozessintegration von Einschnitt-, Aufheiz-und Fügeoperation als Grundlage eines robusten Inline-Thermoclinch-Prozesses vorgenommen. Für die Strukturana-

“…More recently, injection molding was brought into the high strength polymer market through the use of solid pre‐impregnated sheets . Reinforcement fabrics are first impregnated with thermoplastic (Polypropylene or Polyamide are the most common) into sheet format using compression molding or double belt pressing.…”

The use of injection molding to impregnate fabric reinforcements and produce carbon or glass reinforced thermoplastic composites opens the way for high volume mass production at reasonable cost, high strength, and lightweight products. Variable mold temperature together with non‐standard injection parameters allows the proper impregnation of woven carbon and glass reinforcements with standard low viscosity polymers. Testing of the injected composite parts showed a clear increase in mechanical strength. POLYM. ENG. SCI., 58:560–567, 2018. © 2018 Society of Plastics Engineers
