Multi-material designs with tailored material properties, such as hybrid parts of metals and thermoplastics, are a key factor for implementing novel lightweight solutions, e.g. in the transportation sector. Due to the importance of sufficient adhesion between the components, the joining zone is often enlarged by applying different surface structuring methods. In this study, Ti-6Al-4V samples with different types of micron-sized surface structures were produced by electron beam melting. The obtained structures were characterized by means of optical microscopy and tactile or optical roughness measurements. Thermal direct joining was used to connect those metal samples to fiber-reinforced PEK. Moreover, titanium samples were adhesively bonded utilizing a one-component epoxy and a thermoplastic adhesive, respectively. Metallographic cross-sections of all bonded sample types were prepared. Tensile shear tests were conducted and monitored via in-situ optical strain measurements by digital image correlation. In this contribution, the high potential for lightweight applications will be discussed in-depth.
