[{"report_number":"409779252","type":"report","status":"public","abstract":[{"text":"In diesem Forschungsprojekt wurde ein Messverfahren zur Bestimmung akustischer Materialparameter von Polymeren im Ultraschallfrequenzbereich entwickelt. Das Verfahrens sollte, die üblichen standardisierten Prüfmethoden erweitern, die bislang primär im quasistatischen oder niederfrequenten Bereich eingesetzt wurden. Im Gegensatz zu bestehenden Verfahren wie dem Zeitstandversuch oder der Dynamisch Mechanischen Analyse (DMA) nach [DIN6721] sollte die neue Methode eine nicht-invasive Charakterisierung der (visko-)elastischen Materialparameter im Frequenzbereich von 0,75 MHz bis 2,5 MHz ermöglichen. Das entwickelte Ultraschallmesssystem arbeitet nach dem Puls Echo-Prinzip und kann eine räumlich segmentierte, ringförmige Anregung erzeugen. Die Bestimmung der frequenzabhängigen Materialparameter geschieht hierbei über ein inverses Verfahren. Die Ergebnisse des Projekts zeigen, dass die Segmentierung der Anregung, die Geometrie der Probe sowie das Puls-Echo-Messprinzip die Messergebnisse sowie die Sensitivität gegenüber Scherparametern wesentlich beeinflussen. Im Rahmen des Projektes wurde auch eine statistische Auswertung des Optimierungsverfahrens hinsichtlich transversal-isotroper Materialsymmetrie mit Rayleigh-Dämpfung durchgeführt. Die Ergebnisse zeigen, dass das entwickelte Verfahren gute Konvergenzeigenschaften aufweist und sich durch verbesserte Robustheit auszeichnet.","lang":"ger"},{"lang":"eng","text":"This research project involved developing a measurement method to determine the acoustic material parameters of polymers within the ultrasonic frequency range. The aim of this method is to extend the range of standardised tests that operate in the quasi-static or low-frequency range. In contrast to existing methods such as the creep test or dynamic mechanical analysis according to [DIN6721], the developed method is capable of non-invasive characterisation of the (visco-)elastic material parameters in the frequency range of 0,75 MHz bis 2,5 MHz. The developed ultrasonic measurement setup utilises the pulse-echo principle and can generate a spatially segmented, ring-shaped excitation. The frequency-dependent material parameters are determined using an inverse method. The final results of the project show that the segmentation of the excitation, the geometry of the specimen and the pulse-echo measurement principle have a significant influence on the measurement results and the sensitivity to shear movements. As part of the project, a statistical evaluation of the optimisation process was also carried out with regard to transversely isotropic material symmetry with Rayleigh damping. The results show that the developed process has good convergence properties and is characterised by improved robustness."}],"user_id":"32616","department":[{"_id":"49"}],"project":[{"name":"Vollständige Bestimmung der akustischen Materialparameter von Polymeren","_id":"89"}],"_id":"65426","language":[{"iso":"ger"}],"keyword":["Materialcharakterisierung","Polymer","Inverses Problem","Ultraschall","Optimierung"],"publication_status":"published","citation":{"ama":"Dreiling D, Itner D, Birk C, Gravenkamp H, Henning B. <i>Vollständige Bestimmung der akustischen Materialparameter von Polymeren II</i>.

Particularly when drugs have to be transported across biological barriers, suitable drug delivery systems are of importance. In recent years responsive delivery systems have been developed which enable a controlled drug release depending on internal or external stimuli such as changes in pH, redox environment or light and temperature. In some studies delivery systems with reactivity against two different stimuli were established either to enhance the response by synergies of the stimuli or to broaden the window of possible trigger events. In the present review numerous exciting developments of pH-, light- and redox-cleavable polymers suitable for the preparation of smart delivery systems are described. The review discusses the different stimuli that can be used for a controlled drug release of polymer-based delivery systems. It puts a focus on the different polymers described for the preparation of stimuli-sensitive systems, their preparation techniques as well as their stimuli-responsive degradation. © 2022 The Authors.

The raw material is a polymer powder which is melted layerwise by the use of laser energy. Especially for the production of single parts, small series, individualized and complex structures, the technology is yet established in few branches. However, inhomogeneous and hardly controllable thermal effects during manufacturing limit the build reproducibility. The present work focuses on temperatures within so-called part cakes, their time dependency and their influence on process quality. Therefore, a temperature measurement system is implemented into a commercial laser sintering machine. Based on the experimental data a model to simulate heat transfer within part cakes is set up. Individual thermal histories during processing are successfully correlated with position dependent powder ageing effects. Another focus is on the analysis of a recycling optimized material. First results of correlations between thermal histories and part properties are shown in order to provide an outlook to further research. The data and knowledge gained through this work can be used to understand thermal effects in greater depth and to increase the process quality via optimizations.","lang":"eng"}]},{"article_type":"original","department":[{"_id":"9"},{"_id":"876"},{"_id":"321"}],"user_id":"22833","_id":"52208","status":"public","type":"journal_article","doi":"10.1007/s40095-015-0200-2","main_file_link":[{"url":"Primary energy demand \u0002 Energy efficiency within industry \u0002 Polymer processing"}],"volume":7,"author":[{"first_name":"Diana","last_name":"Khripko","full_name":"Khripko, Diana"},{"last_name":"Schlüter","orcid":"0000-0002-2569-1624","id":"103302","full_name":"Schlüter, Alexander","first_name":"Alexander"},{"first_name":"Benjamin","full_name":"Rommel, Benjamin","last_name":"Rommel"},{"first_name":"Michele","full_name":"Rosano, Michele","last_name":"Rosano"},{"full_name":"Hesselbach, Jens","last_name":"Hesselbach","first_name":"Jens"}],"date_updated":"2025-04-01T08:40:14Z","intvolume":"         7","page":"225-233","citation":{"ieee":"D.

For this process compounding extruders are used which mostly involve tightly intermeshing, co-rotating twin screw extruders. These extruders consist of two closely spaced screws which rotate in the same direction and convey the raw material to the screw tip. These screws are surrounded by several barrel modules which heat or cool the material. As the whole design of the machine is modularly arranged the process behavior of a twin screw extruder depends for the main part on the arrangement of the screw and the barrel elements. Until today this arrangement and process optimization is conducted by experienced engineers and with the help of trial-and-error methods. Furthermore, theoretical models are used with which the behavior of the extruder is estimated. As these models are mostly very complex they are only made available with the realization in different software projects. One of the tools is called SIGMA. Within this paper SIGMA is introduced as a software to optimize a twin screw extruder. SIGMA supports the engineer already in the early stages of the extruder arrangement."}],"type":"conference","publication":"Proceedings of the 2010 Summer Computer Simulation Conference"}]
