A master’s thesis at RWTH Aachen University, Institute for Plastics Processing (IKV)

Background and Information:
Foamed sheets made of thermoplastic materials are used, among other
things, for thermal and sound insulation systems. The production
of these foam sheets with CO2 as an environmentally friendly, physical
blowing agent is an important step towards the sustainable production of
foam products. The modelling of the flow and foaming behaviour and the
crystallisation at the exit of the extrusion die have so far mainly been investigated
experimentally and cannot yet fully be described analytically.
The relationships between process parameters (melt temperature, die
pressure), blowing agent formulation (type and quantity of blowing agent)
and the foam sheet properties have not yet been sufficiently modelled. An
Excel-based model developed at the IKV establishes a relationship between
the process conditions and the foaming behaviour, but has so far
only been used for amorphous plastics.
Your task is to extend the existing model to semi-crystalline plastics like
polypropylene. After literature research on the subject, you will expand the
model and validate the assumptions with the help of existing experimental
measurements.
Basic knowledge of plastics rheology and modelling is helpful, but not essential.
Working from the home office is very well possible.
