    Abstract

    The object of this study was to understand the phenomenon of voiding around particles in stretching filled polymers below the melting temperature with plate shaped fillers. Injection molded tensile bars of glass flake filled polypropylene with 20 vol% of glass flakes were subjected to axial strains ranging from 0.1% to 1.0% at 130°C to 150°C in a tensile frame. The onset of debonding in glass flake filled polypropylene at these temperatures was readily identified from stress-strain curves in tensile tests. Substantial void growth was observed around the flakes at strains as low as 0.5% and 1%. Furthermore, voids were seen to develop all around the glass flakes rather than just at the ends along the stretch direction.
