    Abstract

    Stress-strain curves under uniaxial tension have been evaluated at temperatures ranging from room temperature to 145°C for glass bead filled polypropylene, glass flake filled polypropylene and unfilled polypropylene. Debonding of the fillers in the elastic regime leads to growing voids in the composites, which affects the yield point and the plastic deformation of the expanded composites. Models were fitted to the elastic and plastic regimes of deformation in the various materials at different temperatures.
