Abstract

The structures of dispersion-filled polymer composite materials and their key characterizing parameters are considered. A number of modern models used to describe the rheological properties of dispersion-filled polymer composite materials are analyzed. A generalized mathematical model is proposed that relates relative viscosity to the parameters of the disperse structure. Using dispersion-filled polymer composite materials with various average particle sizes (glass beads, marshalit, and white carbon) as examples, it is demonstrated that the presented model allows one to make a description based on structural parameters for the dependence of the effective viscosity of the studied dispersions over the entire range of filler contents for all disperse systems with various polymer matrices and fillers. The application of this approach in technological practice allows one to estimate the viscosities of melts based on the parameters of a given type of dispersion-filled polymer composite material structure.
