A Deformational Mechanism in Particulate Filled Glassy Polymers

Abstract

The stress-strain behavior of glass bead filled polystyrene, styrene- acrylonitrile, ABS, and PPO composites is studied at various temperatures below their glass transition temperature. Earlier studies of bead filled composites indicated that the addition of filler decreases toughness and ultimate elongation. Results show this is true for certain conditions; however, it is also possible for such composites to have higher toughness and ultimate elongation than the unfilled matrices. A deformational mechanism, involving crazing of the matrix, is proposed which explains this behavior.
