Notes:
Relaxation and stress-strain behavior of SAN-glass bead composites are studied above the glass transition temperature. The strain imposed on the polymeric matrix of the composite is defined as ∊p = ∊c/(1 - φ⅓). 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 + ∊p). 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 ∊p. The relaxation modulus increases with increasing the filler concentration and can be predicted by a modified Kerner equation at 110°C.
