Especially the specific surface area of reduced graphene oxide was selectively influenced by controlled drying of the material. The different types of reduced graphene oxide particles were used to produce epoxy-amine composites that significantly change their curing behaviour and mechanical properties. A variety of surface areas and compositions were prepared by combination of a fast heating rate and different drying methods. The combination of freeze drying with a fast heating rate leads to a large specific surface area of 680 m2/g. The morphologies of the particles were observed by scanning electron microscope and the BET surface area was measured with nitrogen-physisorption. The exfoliation quality was measured by XRD. The generated graphene oxide and thermally reduced graphene oxide particles were mixed with epoxy-amine resin. The curing behaviour was studied with rheological and differential scanning calorimetry (DSC) measurements. We observed that different surface functionalities lowers the Glass transition temperature and the gel time of an epoxy-amine curing system. In addition, we found that generated graphene oxide acts as flexibilizer. An increase of the deformation from 2.5 mm to 3.1 mm was measured by Erichsen Cupping Test.}}, author = {{Wolk, Andreas and Rosenthal, Marta and Weiß, Julia and Voigt, Markus and Wesendahl, Jan-Niklas and Hartmann, Marc and Grundmeier, Guido and Wilhelm, Rene and Meschut, Gerson and Tiemann, Michael and Bremser, Wolfgang}}, issn = {{0300-9440}}, journal = {{Progress in Organic Coatings}}, pages = {{280--289}}, title = {{{Graphene oxide as flexibilizer for epoxy amine resins}}}, doi = {{10.1016/j.porgcoat.2018.05.028}}, year = {{2018}}, } @article{20281, abstract = {{The newly developed joining-by-forming technology “shear-clinching”, features a potentially single-stage process for joining UHSS without requiring any additional elements. Foundational studies have focused on the functionality of shear-clinching at a one-element sample. To ensure the safety of the industrial application of the shear-clinching technology, an investigation with component-like samples with several joints is required. This paper presents a detailed analysis of the material behaviour during the shear-clinching process with multi-element specimens to evaluate the influence of the neighbouring joints. In order to describe the influence of the neighbouring joints, the deformations resulting from the bending and material displacement are recorded without contact after the joining process: locally around the joining point and globally over the entire sample size. To minimize such bending effects, a tool-sided adaptation is provided. The results show the high potential of shear-clinching joining by UHSS and give further recommendations for future multi-material application.}}, author = {{Han, Daxin and Hörhold, Réjane and Müller, Martin and Wiesenmayer, Sebastian and Merklein, Marion and Meschut, Gerson}}, issn = {{1662-9795}}, journal = {{Key Engineering Materials}}, pages = {{389--396}}, title = {{{Shear-Clinching of Multi-Element Specimens of Aluminium Alloy and Ultra-High-Strength Steel}}}, doi = {{10.4028/www.scientific.net/kem.767.389}}, year = {{2018}}, } @article{19755, author = {{Meyer, Sebastian and Meschut, Gerson and Vogt, Hendrik and Behrens, Bernd-Arno and Hübner, Sven and Neumann, André}}, issn = {{0043-2288}}, journal = {{Welding in the World}}, pages = {{565--574}}, title = {{{Application of self-piercing nuts during hot forming of 22MNB5}}}, doi = {{10.1007/s40194-018-00688-8}}, year = {{2018}}, } @article{19394, author = {{Meschut, Gerson and Teutenberg, Dominik and Wünsche, Marc}}, issn = {{1619-1919}}, journal = {{adhäsion KLEBEN & DICHTEN}}, pages = {{16--21}}, title = {{{Prüfkonzept für geklebte Stahl/CFK-Strukturen}}}, doi = {{10.1007/s35145-015-0513-6}}, year = {{2018}}, } @article{20136, author = {{Meyer, Sebastian and Meschut, Gerson and Behrens, Bernd-Arno and Vogt, Hendrik and Neumann, Andre}}, journal = {{Werkstattstechnik online}}, title = {{{Funktionsintegration in der Warmblechumformung}}}, year = {{2018}}, } @inproceedings{45490, author = {{Vogelsang, Christoph and Borowski, Andreas and Kulgemeyer, Christoph and Riese, Josef}}, booktitle = {{Qualitätsvoller Chemie- und Physikunterricht - normative und empirische Dimensionen.
