Of paramount importance for the tailored mechanical properties these composite materials exhibit is the type and geometry of the fibre weave. Especially continuous fibre-reinforced thermoplastic composites are fabricated as laminates and subsequently exposed to forming processes which alter the geometry of the fibres unit cell and thus the local mechanical properties of the material. An approach utilising broadband ultrasonic waves is proposed to non-destructively determine the geometry of the unit cell of the weave.\r\n\r\nThe dispersive behaviour of woven fibre-reinforced sheets is described in accordance with the Flouquet-Bloch theorem as a phononic crystal. In order to develop a model for a description of these periodically structured waveguides, the smallest repeating unit of the wave is modelled with periodic boundary conditions. The resulting dispersion diagram exhibits similarities to that of a homogeneous plate, but additionally displays a periodicity in the wavenumber regime, which correspond with the size of the unit cell. Experimental studies of the dispersive behaviour of acoustic waves in woven fibre-reinforced samples also show a periodicity in the wavenumber regime, enabling a measurement procedure of the unit cell geometry.","lang":"eng"}],"project":[{"_id":"157","grant_number":"495847374","name":"FaMOUS: Ein ultraschallbasiertes Messverfahren unter Berücksichtigung viskoelastischer Eigenschaften zur Charakterisierung der Faser-Matrix-Haftung bei Organoblechen sowie deren realitätsnahe Modellierung"}]},{"date_created":"2025-04-25T08:48:10Z","oa":"1","department":[{"_id":"49"},{"_id":"147"}],"type":"conference","citation":{"bibtex":"@inproceedings{Claes_Zeipert_Brandes_Moritzer_Henning_2025, title={Assessment of Fibre-Matrix Adhesion in Reinforced Polymers by Modal Damping of Guided Acoustic Waves}, DOI={<a href=\"https://doi.org/10.71568/DASDAGA2025.052\">10.71568/DASDAGA2025.052</a>}, author={Claes, Leander and Zeipert, Henning and Brandes, Philipp and Moritzer, Elmar and Henning, Bernd}, year={2025} }","ama":"Claes L, Zeipert H, Brandes P, Moritzer E, Henning B.

In particular, thick-walled structures with thicknesses greater than 6 mm offer a high potential for weight savings. This study investigates the cell structures and mechanical properties of injection-molded test specimens. The influence of different thicknesses (6–10 mm) along with different chemical blowing agents (endothermic, exothermic) with varying dosages (0–2 wt%) is analyzed. The investigations reveal that exothermic chemical blowing agents form finer cells consistently to thin-walled structures than endothermic ones. Higher foaming agent content leads to higher pore fractions, with many small cells coalescing into a large open-pore cell network. The mechanical properties depend mainly on the pore content of the sample. The specific tensile properties deteriorate with the use of chemical blowing agents (CFA), whereas the sandwich structure produced with compact edge layers has a positive influence on the specific flexural properties. </jats:p>"}],"publisher":"SAGE Publications","_id":"42515","page":"187-199","volume":59,"user_id":"38212","status":"public","oa":"1","citation":{"bibtex":"@article{Moritzer_Flachmann_2023, title={Morphological and mechanical properties of foamed thick-walled Wood-Plastic-Composite structures}, volume={59}, DOI={<a href=\"https://doi.org/10.1177/0021955x231161175\">10.1177/0021955x231161175</a>}, number={3}, journal={Journal of Cellular Plastics}, publisher={SAGE Publications}, author={Moritzer, Elmar and Flachmann, Felix}, year={2023}, pages={187–199} }","ama":"Moritzer E, Flachmann F.

In addition to the extrusion of decking boards, the material is also used increasingly in injection molding. Depending on the formulation, geometry and process parameters, WPC tends to exhibit irregular filling behavior, similar to the processing of thermosets. In this work, the influence of matrix material and wood fiber content on the flow, mold filling and segregation behavior of WPC is analyzed. For this purpose, investigations were carried out on a flow spiral and a sheet cavity. WPC based on thermoplastic polyurethane (TPU) achieves significantly higher flow path lengths at a wood mass content of 30% than polypropylene (PP)-based WPC. The opposite behavior occurs at higher wood contents due to the different shear thinning behavior. Slightly decreased wood contents could be observed at the beginning of the flow path and greatly increased wood contents at the end of the flow path, compared to the starting material. When using the plate cavity, flow anomalies in the form of free jets occur as a function of the wood content, with TPU exhibiting the more critical behavior. The flow front is frayed, but in contrast to the flow spiral, no significant wood accumulation could be detected due to the shorter flow path lengths.</jats:p>","lang":"eng"}],"publication":"Journal of Composites Science","issue":"10","doi":"10.3390/jcs6100321","language":[{"iso":"eng"}],"article_number":"321","main_file_link":[{"open_access":"1"}],"intvolume":"         6","publication_status":"published","date_updated":"2023-04-26T13:40:41Z","publication_identifier":{"issn":["2504-477X"]},"author":[{"id":"20531","full_name":"Moritzer, Elmar","last_name":"Moritzer","first_name":"Elmar"},{"id":"38212","last_name":"Flachmann","first_name":"Felix","orcid":"0000-0002-7651-7028","full_name":"Flachmann, Felix"},{"id":"38221","full_name":"Richters, Maximilian","last_name":"Richters","first_name":"Maximilian"},{"full_name":"Neugebauer, Marcel","first_name":"Marcel","last_name":"Neugebauer"}],"year":"2022","title":"Analysis of the Segregation Phenomena of Wood Fiber Reinforced Plastics"},{"user_id":"38212","volume":12,"page":"42-44","_id":"26854","language":[{"iso":"ger"}],"date_updated":"2022-01-20T12:13:51Z","intvolume":"        12","year":"2021","title":"Die Fließfront darf nicht brechen","status":"public","author":[{"first_name":"Elmar","last_name":"Moritzer","full_name":"Moritzer, Elmar","id":"20531"},{"id":"38212","last_name":"Flachmann","first_name":"Felix","full_name":"Flachmann, Felix"}],"type":"journal_article","department":[{"_id":"321"},{"_id":"9"},{"_id":"367"},{"_id":"147"}],"date_created":"2021-10-25T13:54:41Z","publication":"Kunststoffe","citation":{"ieee":"E.
