Modeling the viscosity development of epoxy resins during injection of the RTM process. - In: AIP conference proceedings, ISSN 1551-7616, Bd. 1779 (2016), 070002, insges. 5 S.
The development of, in particular RTM, processes for fiber reinforced composite parts is driven by cost reduction that can be achieved by shorter cycle times. The main sub processes are the injection and the curing time of the resin. Both depend directly on resin properties. During the injection phase the viscosity of the resin is a main factor for the flow rate. Additionally, the wetting of fibers and within that the void formation is influenced. The cure of the resin is the most time intensive sub process. In this paper a new model for the description of the resin viscosity development during the injection phase using the cumulative Weibull distribution function is presented. A study of the isothermal viscosity development of numerous resins has been conducted in a wide temperature range ascertaining the applicability. New possibilities for advanced resin selection and a more accurate modeling of the void formation during an injection phase of the RTM process are shown to confirm the benefit of this model.

Energy balance analysis of the feed zone of grooved barrel single screw extruders. - In: AIP conference proceedings, ISSN 1551-7616, Bd. 1779 (2016), 030011, insges. 5 S.
The energy balance in the feed zone of grooved barrel single screw extruders is important for design and operation of such extruders. Experimental investigations with different bulk materials were undertaken to obtain further insight into the energy balance of the feed zone. The energy balance considers the enthalpy change resulting from temperature and density increase as a result of screw drive power and heat flow in the barrel. Experimental results show a decreasing solid bed temperature for decreasing residence times. In addition, with a reduced gap in the throttle with constant throughput, the pressure increases resulting into various deformation mechanisms of solid particles. The energy required for the deformation of solid particles into a solid bed elevates the specific screw drive power and heat generation. It is shown that the compression behavior of bulk materials is temperature-dependent and influences the energy balance in the feed zone.
