  abstract     = {{Polymer composites represent the industry standard in injection molding for the production 
of plastic components with increased requirements in terms of heat resistance and stiffness. In the 
field of laser sintering (LS), these materials are less common so far. In order to extend the available 
material variety for the LS process, new ceramic-filled Polyamide 613 powders are investigated
within the scope of this work. Here, the resulting properties from two different powder production 
methods are compared. One filled powder is produced by dry blending and the other powder with 
the same filler and filling ratio is produced by encapsulating the filler particles inside the polymer 
particles within the dissolution-precipitation process. It was found that encapsulating the filler 
particles can provide certain benefits for the processability, for example an improved powder 
flowability or better filler dispersion. However, encapsulating the filler also alters the thermal 
properties of the precipitated powder.}},

  abstract     = {{In a punch-bending machine, wire products are manufactured for a wide range of industrial sectors, such as the electronics industry. The raw material for this process is flat wire made of high-strength steel. During the manufacturing process of the flat wire, residual stresses and plastic deformations are induced into the wire. These residual stresses and deformations fluctuate over the length of the semi-finished product and have a negative effect on the final product quality. Straightening machines are used to reduce this influence to a minimum. So far, the adjustment of a straightening machine has been performed manually, which is a lengthy and complex task even for an experienced worker. This inevitably leads to the use of inefficient straightening strategies and causes high rejection rates in the entire production process. Due to a lack of sensor information from the straightening operation, application of modern feedback control methods has not been practicable. This paper presents a novel design for a straightening machine with an integrated, precise straightening force measurement. By simultaneously monitoring the position of the straightening rollers, state variables of the straightening operation can be derived. Additionally, a tension control for feeding the flat wire is introduced. This is implemented to mitigate the disturbing effects caused by irregularities in the wire-feeding process. In the results of this article, the high precision of the developed force measurement design and its possible applications are shown.}},

  abstract     = {{Fused deposition modeling (FDM) is an additive manufacturing process that can be used to manufacture three-dimensional thermoplastic components layer by layer. One disadvantage of FDM is the shrinkage of the components during the manufacturing process. The filament is molten in the nozzle, deposited layer by layer, and cools down again. During solidification, the filament shrinks inhomogeneously in the x/y/z direction, which leads to distortion of the component geometries. Particularly with higher nominal lengths and complex local geometries, there is a need for optimization with regard to dimensional accuracy. The aim of this paper is to counteract this on the software side with global as well as local shrinkage factors. The expected shrinkage within a layer is predicted with an in-house developed software. The geometric accuracy of the model is verified by experimental investigations on cylindrical test specimens. In these, the so-called clover effect occurs as a result of the shrinkage. The circular shape of the deposited layer is deformed by the distortion in the x–y plane comparable to a clover. Finally, the results are validated by analyzing a demonstrator in the form of a bracket.}},

Diese Arbeit erforscht die hybride Kombination von pressgehärtetem Stahl und kohlenstofffaserverstärktem Kunststoff. Ausgehend von einer Analyse bestehender Karosseriestrukturen erfolgt ein Konzept für eine hybride B-Säule. Das Potential zur Gewichtsreduzierung durch das hybride Bauteilkonzept wurde dabei zu 57 % identifiziert, welches jedoch nur bei Sicherstellung einer intakten Grenzfläche erreicht wird. Zur Erlangung der Grenzflächenfestigkeit bei charakteristischen Belastungsprofilen wurde ein Verfahren zur Einbringung makroskopischer Formschlusselemente im Presshärteprozess entwickelt. Durch diese Formschlusselemente wird eine Steigerung der Scherfestigkeit der hybriden Komponenten von über 300 % erreicht. Die gewonnenen Erkenntnisse werden abschließend zur Auslegung einer hybriden B-Säule angewendet.}},

  abstract     = {{Die weltweit erzeugten Emissionen müssen in allen emittierenden Sektoren signifikant gesenkt werden, um die Auswirkungen des Klimawandels zu reduzieren. Dies ist unter anderem durch die energieeffiziente Wiederverwertung vorhandener Ressourcen und damit der Einstellung einer nachhaltigen Kreislaufwirtschaft möglich. Aufgrund der hohen erforderlichen Energiemenge in der primären Herstellung von Aluminium existieren hier im Vergleich zu anderen Konstruktionswerkstoffen große Einsparpotentiale. Mit dem in dieser Arbeit erforschten reibungsinduzierten Recyclingverfahren (RIR) wird eine alternative und energieeffiziente Prozessroute zum direkten Recycling von unterschiedlichen Aluminiumschrotten geschaffen. Zur Charakterisierung der Prozessroute werden u. a. die Erkenntnisse aus sich gegenseitig unterstützenden experimentellen und theoretischen Untersuchungen zu den Vorgängen der der Verdichtung, Plastifizierung als auch Extrusion der recycelten Profile dargelegt. Die Einflüsse unterschiedlicher Eingangsgrößen wie z. B. der Werkzeuggestaltung oder der Verarbeitung unterschiedlicher Legierungen werden zudem zur zukünftigen Auslegung des Prozesses erläutert. Aus der abschließenden energetischen Bilanzierung kann geschlossen werden, dass aufgrund der geringeren Verarbeitungstemperatur signifikante Energieersparnisse bei Verwendung des RIR im Vergleich zu den konventionellen Produktionsstrategien erzielt werden können.}},
