Lightweight design using wood fibers as sustainable reinforcement for thermoplastics might be one solution. The processing of wood fibers requires special attention to the applied thermal load. Even at low processing temperatures, the influence of the dwell time, temperature and shear force is critical to ensure the structural integrity of fibers. Therefore, this article compares different compounding rates for polypropylene with wood fibers and highlights their effects on the olfactory, visual and mechanical properties of the injection-molded part. The study compares one-step processing, using an injection-molding compounder (IMC), with two-step processing, using a twin-scew-extruder (TSE), a heating/cooling mixer (HCM) and an internal mixer (IM) with subsequent injection molding. Although the highest fiber length was achieved by using the IMC, the best mechanical properties were achieved by the HCM and IM. The measured oxidation induction time and volatile organic compound content indicate that the lowest amount of thermal damage occurred when using the HCM and IM. The advantage of one-time melting was evened out by the dwell time. The reinforcement of thermoplastics by wood fibers depends more strongly on the structural integrity of the fibers compared to their length and homogeneity}, language = {en} } @inproceedings{BleyHommel2022, author = {Bley, Sandra and Hommel, Mandy}, title = {Ingenieurp{\"a}dagogik in Bayern- ein Portrait der Standorte}, series = {7.

Due to the increasing demand for batch-size-one production, every product needs specific manufacturing processes. Usually, employees determine these manufacturing steps with provided product data. This research proposal aims to contribute to the extraction of machining processes from product data and their assignment to suitable machinery. We plan to develop an organic computing system based on artificial intelligence methods to solve these problems by including customer-specific designs and employee expertise. The overall objective is to support employees in manufacturing facilities by simplifying the manufacturer and customer interaction.}, language = {en} } @inproceedings{Rabold2022, author = {Rabold, Andreas}, title = {Schallschutz und Schalld{\"a}mmung im Holzbau - Vorplanung und Nachweisverfahren}, series = {Fortschritte der Akustik - DAGA}, booktitle = {Fortschritte der Akustik - DAGA}, organization = {Deutsche Gesellschaft f{\"u}r Akustik e.V.}, year = {2022}, language = {de} } @inproceedings{RaboldMeckingHuber2022, author = {Rabold, Andreas and Mecking, Simon and Huber, Anton}, title = {Schalltechnische Aspekte bei NaWaRo-D{\"a}mmstoffen: Details aus dem Inneren}, series = {Bauphysik \& Geb{\"a}udetechnik}, booktitle = {Bauphysik \& Geb{\"a}udetechnik}, organization = {Forum Holzbau}, isbn = {978-3-906226-41-5}, year = {2022}, language = {de} } @inproceedings{Schanda2022, author = {Schanda, Ulrich}, title = {Schallschutzprognose mit Methoden der KI - erste Gedanken}, series = {Fortschritte der Akustik - DAGA}, booktitle = {Fortschritte der Akustik - DAGA}, organization = {Deutsche Gesellschaft f{\"u}r Akustik e.V.}, year = {2022}, language = {de} } @inproceedings{SchoepferKruseMayretal.2022, author = {Sch{\"o}pfer, Fabian and Kruse, Tobias and Mayr, Andreas R. and Schanda, Ulrich}, title = {Erfahrungen mit der DIN EN 15657:2017-10 und dem Empfangsplattenpr{\"u}fstand an der TH Rosenheim}, series = {Fortschritte der Akustik - DAGA}, booktitle = {Fortschritte der Akustik - DAGA}, organization = {Deutsche Gesellschaft f{\"u}r Akustik e.V.}, year = {2022}, language = {de} } @inproceedings{SchoepferKruseWeinzierletal.2022, author = {Sch{\"o}pfer, Fabian and Kruse, Tobias and Weinzierl, Johanna and Mayr, Andreas R. and Schanda, Ulrich}, title = {Experiences with source characterization methods within and beyond the scope of EN 15657}, series = {Proceedings of Inter-Noise 2022}, booktitle = {Proceedings of Inter-Noise 2022}, year = {2022}, language = {en} } @inproceedings{WeberSchandaSchoepfer2022, author = {Weber, Katharina and Schanda, Ulrich and Sch{\"o}pfer, Fabian}, title = {Lautheit als Messgr{\"o}ße f{\"u}r die Trittschall{\"u}bertragung}, series = {Fortschritte der Akustik - DAGA}, booktitle = {Fortschritte der Akustik - DAGA}, organization = {Deutsche Gesellschaft f{\"u}r Akustik e.V.}, year = {2022}, language = {de} }
