Studies of Stress-Strain Behavior of SAN/Glass Bead Composites above the Glass Transition Temperature

Abstract

Relaxation and stress-strain behavior of glass bead/styrene- acrylonitrile composites are studied above the glass transition temperature. Stress relaxation data for the filled polymer which is independent of strain can be calculated by multiplying the relaxation modulus (at a certain strain) by (1 plus strain in the polymer matrix). Stress-strain curves at constant strain rate and for different concentrations of the filler can be shifted to form a master curve independent of filler content if the tensile stress is plotted versus strain in the polymer matrix. The relaxation modulus increases with increasing the filler concentration and can be predicted by a modified Kerner equation at 110 C.
