    Biography

      Frederik Desplentere graduated as a master in mechanical engineering in 1999. In 2007, he obtained his Phd in materials engineering. From 2004 on, he is involved in the applied research on polymer processing combining material characterization, numerical simulations and validation experiments valid for injection molding, extrusion technology and thermoforming. Up to date lab equipment is present both to perform material characterization and instrumented processing. In 2013, Frederik Desplentere became a professor within the materials engineering department of KU Leuven Bruges Campus. Nowadays, he is the head of the Propolis research group which counts 20 members. The research group is mainly focusing on sustainable polymer processing; several projects are performed on the processing of recycled or biobased materials. 


    Abstract

    Measuring the shear rheology for highly temperature sensitive materials is challenging. Material characterization tools are slow compared to industrial processing. Using numerical simulations will help to illustrate the challenges for both the industrial processing and the material characterization.  Three measuring techniques to obtain shear viscosity will be compared and discussed based on recent developments within a research project performed within KU Leuven.
