Ultrasonic Joining (U-Joining) is a novel friction-based joining technique that produces through-the-thickness reinforced hybrid joints between surface-structured metals and thermoplastics. The process feasibility has been successfully demonstrated to join unreinforced or fiber-reinforced polymer parts by applying horizontal vibration. However, intense tool wear was observed for the explored co...

In this study, quasi-unidirectional continuous fiber reinforced thermoplastics (CFRTs) are joined with metal sheets via cold formed cylindrical, elliptical and polygonal pin structures which directly pressed into the CFRT component after local infrared heating. comparison to already available studies, unique novelty is use of non-rotational symmetric for CFRT/metal hybrid joining. Thus, a varia...

The widespread application of thermoplastic polymers in different aspects of industries has motivated researchers and companies to improve and upgrade their forming, joining and assembling processes to overcome their limitations. One of the newest joining methods of thermoplastics is friction stir welding which is based on frictional heat generated through contact between a rotating tool and th...

Abstract To determine the characteristics of new suction concepts for hybrid laminar flow control (HLFC) a modular flat plate wind tunnel model is investigated in DNW-NWB facility. This approach allows detailed examination consideration realistic boundary layer conditions. The following evaluation reveals effects joining methods between successive panels and other surface disturbances porous ma...

Abstract The Collaborative Research Center 1153 is investigating an innovative process chain for the production of hybrid components. workpieces are first joined and then formed by cross-wedge rolling. Pinion shafts were manufactured to investigate behavior joining zone under increased complexity forming process. For this purpose, six types produced three processes into pinion shafts. reference...
