Abstract
A theoretical expression has been derived to describe the strain behavior of rigid plastic composites containing spherical filler particles. By combining the predicted ultimate strength values with the appropriate modulus relationship, the complete stressβstrain history and corresponding fracture energy may be estimated. The theoretical predictions were compared with experimental values obtained for a generalβpurpose polyester resin containing spherical glass beads. The influence of silane coupling agents and filler adhesion was also evaluated. Although the experimental values showed considerable scatter, the general trend agreed fairly well with the theoretical predictions.

Tensile properties of both a binary material, i.e., polystyrene (PS) reinforced by 15 vol % of glass beads, and ternary composites, i.e., showing either a maleated styrene/ethylene-co-butylene/styrene copolymer or a styrene-co-methacrylic acid copolymer (SAMA) adduct at the PS/glass-beads interface,
Dynamic mechanical behaviors of binary and ternary particulate composites are investigated to test for the influence of the nature of a polymeric adduct, i.e., maleated styrene ethylene-co-butylene styrene (SEBS) or styrene-co-methacrylic acid (SAMA) copolymers, at the polystyrene (PS)/glass-beads i
