Modeling, processing and optimization of highly-filled polymer wood fiber composites 

Biocomposites are a critical ingredient in the context of overarching societal efforts to increase the use of renewable materials. Therefore, the use of polymer with natural fiber reinforcements is expected to increase significantly. A current drive for polymer biocomposites is to maximize the use of renewable content in mass production systems. However, the full potential …

Advanced rheological characterization of cellulose based systems

Processing, e.g. extrusion, injection molding, typically involves rheologically complex materials in complex flow configurations. The deformation history therein experienced by materials is generally characterized by a series of shear, extensional, or a combination of the two deformations, at high isotopic pressures and temperatures. Therefore, a fundamental understanding of the material response in simple shear and …

Development of a new rheometer system at MAX IV

Rheometry explores the relationship between forces and motion through (continuum) constitutive relations and suitably defined material functionsi. Rheometry is important for soft matter from two main reasonsii: (i) to investigate correlations between molecular structure and material behavior and (ii) to attempt the prediction of flow behavior in complex situations using material parameters determined in simple, …
