The detection principle is based on a secondary electron conversion holder with an exchangeable aperture strip allowing its acceptance angle to be tuned from 3 to 98 mrad. The contrast mechanism and performance were investigated using freestanding nanometer-thin carbon membranes. The results demonstrate that the detector can be optimized either for most efficient signal collection or for maximum image contrast. The designed setup allows for the imaging of thin low-density materials that otherwise provide little signal or contrast and for a clear end-point detection in the fabrication of nanopores. In addition, the detector is able to determine the thickness of membranes with sub-nanometer precision by quantitatively evaluating the image signal and comparing the results with Monte Carlo simulations. The thickness determined by the dark-field transmission detector is compared to X-ray photoelectron spectroscopy and energy-filtered transmission electron microscopy measurements.}}, author = {{Emmrich, Daniel and Wolff, Annalena and Meyerbröker, Nikolaus and Lindner, Jörg and Beyer, André and Gölzhäuser, Armin}}, issn = {{2190-4286}}, journal = {{Beilstein Journal of Nanotechnology}}, pages = {{222--231}}, title = {{{Scanning transmission helium ion microscopy on carbon nanomembranes}}}, doi = {{10.3762/bjnano.12.18}}, year = {{2021}}, } @inproceedings{21442, author = {{Tinkloh, Steffen Rainer and Wu, Tao and Tröster, Thomas and Niendorf, Thomas}}, keywords = {{Micromechanics, Fast Fourier Transform (FFT), Reduced Order Modelling, Homogenization}}, title = {{{Development of a submodel technique for FFT-based solvers in micromechanical analysis}}}, year = {{2021}}, } @article{23977, author = {{Tölle, Lisa and Hopp , Matthias}}, journal = {{Kunststoffland NRW Report }}, title = {{{Recycling faserverstärkter Kunststoffe zu Ende gedacht… }}}, year = {{2021}}, } @inproceedings{20857, author = {{Camberg, Alan Adam and Tröster, Thomas and Latuske, Clemens}}, location = {{Wolfsburg}}, publisher = {{Springer}}, title = {{{Development of a hybrid crash-relevant car body component with load-adapted thickness properties: Design, manufacturing and testing}}}, doi = {{https://doi.org/10.1007/978-3-662-62924-6_28}}, year = {{2021}}, } @inproceedings{20858, author = {{Camberg, Alan Adam and Tröster, Thomas and Wingenbach, Nils and Hielscher, Christian and Grenz, Julian}}, location = {{Wolfsburg}}, publisher = {{Springer}}, title = {{{A new numerical method for potential anaylsis and design of hybrid components from full vehicle simulations: Implementation and component design}}}, doi = {{https://doi.org/10.1007/978-3-662-62924-6_30}}, year = {{2021}}, } @article{22518, author = {{Triebus, Marcel and Gierse, Jan and Marten, Thorsten and Tröster, Thomas}}, issn = {{1757-8981}}, journal = {{IOP Conference Series: Materials Science and Engineering}}, location = {{Virtual - Stuttgart}}, publisher = {{IOP Publishing Ltd}}, title = {{{A new Device for Determination of Forming-Limit-Curves under Hot-Forming Conditions}}}, doi = {{10.1088/1757-899x/1157/1/012052}}, year = {{2021}}, } @techreport{29807, author = {{Linnig, Caterina and Tröster, Thomas}}, publisher = {{Deutsche Bundesstiftung Umwelt (DBU)}}, title = {{{Entwicklung eines neuartigen Reinigungsverfahrens für recycelte Kohlenstofffasern}}}, year = {{2021}}, } @inproceedings{25283, author = {{Moritzer, Elmar and Hecker, Felix and Elsner, Christian Lennart and Hirsch, André}}, booktitle = {{Proceedings of 36th Annual Meeting of Polymer Processing Society (PPS-36)}}, location = {{Montreal, Canada}}, title = {{{Influences of Temperature-Dependent Boundary Conditions on Component Properties in Arburg Plastic Freeforming}}}, year = {{2021}}, } @article{23944, author = {{Moritzer, Elmar and Richters, Maximilian}}, journal = {{Journal of Applied Polymer Science}}, publisher = {{Wiley }}, title = {{{Characterization of wood-filled thermoplastic polyurethane for the injection modling process}}}, year = {{2021}}, } @article{23948, author = {{Moritzer, Elmar and Richters, Maximilian and Hillemeyer, Johannes and Krassmann, Dimitri}}, journal = {{Joining Plastics}}, title = {{{Mit dem Schraubblind-Durchsetznieten Metallteile mit Composites bei einseitiger Zugänglichkeit verbinden}}}, year = {{2021}}, } @book{22032, abstract = {{The Arburg Plastic Freeforming (APF) is an additive manufacturing process which allows the production of three-dimensional thermoplastic components in layers. The components are produced by depositing fine, molten plastic droplets. The main advantage of the APF is the open-parameter control of the associated machine system. Thus, the process parameters can be optimized for individual applications. A special and new application of the APF is the production of interconnecting porous structures. As this is a novel approach with this manufacturing process, the general producibility and reproducibility must first be proven. Therefore, the relevant process parameters with an influence on the open-pored structures are identified. The volume of the individual plastic droplets, the distance between the droplets and the layer thickness are the three decisive influencing factors. With the use of analysis methods, the free spaces created in the structure are described by a uniformly constructed, interconnected pore structure. This means that the pores are interconnected in three dimensions. Reproducibility is evaluated by repeated production and thru the changed conditions during the manufacturing process. In addition, the multiplication and a change of geometry are evaluated in such a way that there is no influence on the pore size. Irregularities when depositing the first layer are caused by unevenness of the building platform. A suitable test arrangement is set up to determine the liquid permeability. A characteristic value is determined to describe the permeability to liquids.}}, author = {{Moritzer, Elmar and Hirsch, André and Dalmer, C.}}, isbn = {{978-3-030-54333-4}}, pages = {{112--129}}, publisher = {{Springer}}, title = {{{Investigation of Plastic Freeformed, Open-Pored Structures with Regard to Producibility, Reproducibility and Liquid Permeability}}}, doi = {{10.1007/978-3-030-54334-1}}, year = {{2021}}, } @article{24162, author = {{Moritzer, Elmar and Wächter, Julian and Elsner, Christian Lennart}}, journal = {{Macromolecular Symposia}}, number = {{1}}, publisher = {{Wiley}}, title = {{{Investigation of Specific FDM Process Parameters to Optimize the Polymer Discharge of Carbon Fiber Reinforced PEEK}}}, doi = {{10.1002/masy.202000269}}, volume = {{395}}, year = {{2021}}, } @article{24681, author = {{Moritzer, Elmar and Schumacher, Christian}}, issn = {{1022-1360}}, journal = {{Macromolecular Symposia}}, number = {{1}}, title = {{{Stainless Steel Parts Produced by Fused Deposition Modeling and a Sintering Process Compared to Components Manufactured in Selective Laser Melting}}}, doi = {{10.1002/masy.202000275}}, volume = {{395}}, year = {{2021}}, } @inproceedings{24554, author = {{Moritzer, Elmar and Elsner, Christian Lennart and Wächter, Julian and Knoop, Frederick}}, booktitle = {{79th Annual Technical Conference of the Society of Plastics Engineers (ANTEC)}}, title = {{{Investigation and Realization of Watertight FDM Structures Made of Ultem 9085 in Pressurized Systems}}}, year = {{2021}}, }
