Methoden zur Auslegung einer Mensch-Roboter-Kooperation
(2019)
Durch eine neue Generation von Robotern werden Maschinen, die bisher hinter einem Schutzzaun arbeiteten, in den Arbeitsraum eines Industriewerkers versetzt. In der Mensch-Roboter-Kooperation (MRK) werden Schutzzäune durch Sensorik ersetzt, die sich häufig am Roboter befindet. Die neuartigen Roboter sind tendenziell kleiner und leichter als ihre konventionellen Artgenossen, dürfen ihre Tätigkeiten jedoch in nächster Nähe zu einem Menschen ausüben. Wie wirkt sich dies auf den Industriearbeiter aus?
Genau diese Frage ...

Influence Of The Fiber-Matrix-Interaction On The Fracture Behavior Of Regenerated Cellulose Fiber Reinforced Polypropylene
(Society of Plastics Engineers, 2017)
This investigation focuses on the fiber-matrix-interaction of man-made cellulose fibers (RCF) in a PP matrix with an additional MAPP content using an energetic evaluation of the single fiber pull-out test (SFPT). Furthermore glass fibers were characterized for reference purposes. With the SFPT the interfacial shear strength (IFFS) and the critical fiber length (lc) as well as the consumed energy of a fiber pull-out and a fiber rupture were determined. In a following step the resulting values of lc were related to the ...

Fabrication and characterization of ethylene–octene copolymer composites with ionic liquid functionalized carbon nanotubes
(2017-10-16)
Modification of multi-walled carbon nanotubes (MWCNTs) by means of imidazolium ionic liquid (IL) was performed. Structural characterization of funtionalized nanofillers (IL-f-MWCNTs) was made by means of Raman spectroscopy and transmission electron microscopy. MWCNTs and IL-f-MWCNTs were introduced within ethylene octane copolymer (EOC) with octene co-monomer content of 17% by using the masterbatch approach. The efficiency of the carbonaceous nanofiller distribution within the polymer matrix was characterized by means ...

Characterizing the Rheological Behavior of Liquid Silicone Rubber Using a High Pressure Capillary Rheometer
(Society of Plastics Engineers, 2016)
The injection molding process of liquid silicone rubber (LSR) imposes high demands on the injection molding machines and the tools due to the low viscosity of silicone rubber. There is very little data which describes the rheological behavior of LSR and its influencing factors across a range of shear rates.
In this study, the rheological behaviors of different types of LSR were characterized using a high pressure capillary rheometer with an apparent shear rate that ranged from 350 to 4000 1/s. In order to identify ...

Hybrid composite materials made of polypropylene with wood and polyethylene terephthalate fibers
(Society of Plastics Engineers, 2014)
We aim to manufacture injection molded components which consist of thermoplastics reinforced with fibers and which have improved properties (high strength and high notched impact strength). Thus, we intend to access new application fields for the not readily visible area of the automobile interior.

Joining Investigations of Polymer-Metal-Hybrids for Permanantly Non-Leaking Applications
(Society of Plastics Engineers, 2016)
The demand for light-weight construction and economic efficiency has led to the development of light-weight construction strategies, i.e., multi-material design, in many areas of industry. Here, the property profiles of the composite partners are utilized synergetically. Plastic-metal hybrid composites possess a large amount of potential in this regard owing to the weight reduction that can be achieved in the composite and the simultaneous enhancement of the mechanical properties.
Hybrid components have already ...

Development of a Flexible Polymer Joining Center Capable of Performing Multiple Joining Processes Using Different Methods in a Single Cycle
(Society of Plastics Engineers, 2016)
Goal of this research and innovation project is the implementation of a flexible polymer joining center as a prototype machine integrating different friction welding methods. This prototype joining cell combines (a) flexibility by being capable of performing joining processes in any order in a single flow with (b) modularity by integrating unified interfaces for exchanging joining modules, and (c) scalability by offering a wide range of setups for smaller to larger work pieces. Corresponding interfaces to up- and ...

The Manufacture of Hot-Compacted Layered Composite Systems Made of Oriented Semifinished PP-Films
(2014-03-04)
Monoaxial stretched PP-films are used for the manufacture of hot-compacted layered composites. These are layered with stretched co-extruded coupling agent films, and are consolidated to laminates by means of a hot-compaction process, which employs pressure and temperature. This paper aims to examine the influence of the process settings on the properties of the composites during the hot-compaction process. For this purpose, the mechanical values will be determined by means of tensile testing variously compacted and ...

Beitrag zur Herstellung 3-dimensionaler Kunststoffscheiben mit integrierter Funktion zur Veränderung der Transparenz durch Elektrochromie
(kassel university press, 2017)
Ziel dieser Arbeit ist es Möglichkeiten der Kunststoffverarbeitung aufzuzeigen, um feste 3D Bauteile mit elektrochromen (EC) Eigenschaften herzustellen. Die momentanen EC Anwendungen reduzieren sich fast ausschließlich auf plane Fensterscheiben aus Glas für die Gebäudeverglasung. Vereinzelt gibt oder gab es aber auch Anwendungen im Flugzeug- und Automobilbau. Die Anforderungen bezüglich des Schaltverhaltens sind in den erwähnten Bereichen sehr hoch und führen zu einer kostenintensiven Produktion.
