Research Areas

Main scientific areas which are researching in Co-ExIn programme are following:

  • single-screw extrusion (LUT),
  • twin-screw extrusion (WHZ),
  • injection moulding (TUKE),
  • properties of composites NULP).

The Lublin University of Technology (Poland) LUT will present original, patented and as for now unique design solutions activating the grooved feed zone (longitudinal and helical grooves) of single-screw extruders and activating kinematically the extruder’s barrel – the rotating segment of the barrel These innovative extruders will be used to conduct experiments on extrusion of advanced materials, which will determine the influence of design changes in the extruder’s barrel on the technology, effectiveness of plasticizing and the properties of the obtained composite extrudate.

Using its twin-screw extruder, University of Applied Science of Zwickau (Germany) WHZ will demonstrate the influence of changes of the rotational speed of the screws and the temperature in the particular zones of the plasticizing system, as well as other parameters of twin-screw extrusion on the properties of the obtained polymer composites.

Technical University of Kosice (Slovakia) TUKE will use an injection moulding machine to conduct experiments on injection moulding of the received polymer blends, with various technological conditions of the process and changes in the moulding pressure, cooling time and mould design. A strength testing machine will be used for tensile tests determining the influence of filler quantity in thermoplastic composites on changes of mechanical properties during injection moulding.

At the Lviv Polytechnic National University (Ukraine) NULP, different advanced materials will be produced through calandering and rolling, to be processed at LUT, WHZ and TUKE. Moreover, the NULP, by changing the conditions of blending of different types of fillers with the thermoplastic polymer, will show the effect of those conditions on the mechanical, physical and physicochemical properties of the obtained composites.

The above actions will facilitate the realization of the individual tasks of the work package. During the workshops, each of the participants in the meeting will have an opportunity to freely discuss and exchange their ideas, comments and conclusions. The results of the open, unrestricted discussion following the experimental part will be recorded. This will make it possible to achieve the specific goals.
