Polimery 2008, No 7/8, 507
In this review the models applied for the description of non-Newtonian liquids were presented. Highly filled polymer melts showing distinct yield stress are such liquids. The effects of forces of geometrical and physical interactions among the filler particles on the properties were discussed. These interactions forces depend on the type, size and shape of filler particles and in case of fibers also on their orientation. The deformations and flow of fibers assemblies in the melt under shear stress were discussed. The equations used for description of three- or two-dimensionally oriented fibers sets are presented.
Key words: polymer melt, filler, modeling of rheological properties, viscosity, yield stress, shear rate
