n the field of micro systems technology, e.g. for sensors or actuator applications, polymeric materials with functional properties
(e.g. electrical conductivity or magnetic properties) are an interesting alternative to common metallic materials due to their high-
efficient fabrication techniques. The desired functional property spectrum is often realized by addition of functional fillers, which
inevitably influences the injection molding process. Especially the flow-ability and the mold filling behavior change dramatically due
to the fillers. This behavior is critical for the quality of the final part, but cannot be predicted sufficiently until now. At present, the
current standard process monitoring technologies are not adequate to provide enough information to analyze and optimize the filling
behavior. In the presented study, the flow behavior of the highly-filled polymeric materials is characterized with a glass-insert mold
which is designed for direct visual analysis of the flow phenomena. The investigation is carried out using polyamide (PA 6) with ferrite
micro particles of 150µm size. These particles are admixed to the polymer matrix with filler contents of 50 vol.-%, 60 vol.-% and 65
vol.-%, respectively. The flow front is observed during the filling stage with a high-speed camera. The filling behavior is simulated with
commercial software (Mold Flow®), and validated with the real experiment. Based on these investigations, the process ability of highly
filled polymer melts are characterized both by experiment and simulation, with evaluation of the conventional simulation tools for
application in highly-filled polymeric materials.
Biography
Tamara Florian graduated 2010 at the Munich University of Applied Sciences in the field of process engineering. Since then, she is working at the Institute of Polymer Ma-
terials and Plastics Engineering in the field of processing and functionalization of thermoplastic materials. She is mainly concerned with the development of new, functional
materials and their processing properties in the injection molding process. Apart from the consideration of the properties in conventional injection molding, Ms. Florian is
particularly concerned with the micro-injection molding technique.
