Research output: Contribution to conferencePaperpeer-review


In this study, the effect of the number and size of clusters on the fracture behavior of PP and TPO nanocomposites are investigated. The effect of the particle size distribution and injection molding flow profile are also discussed with respect to the effect of filler morphology on the tensile fracture toughness. Fracture pattern and fracture surface were examined by scanning electron microscopy (SEM). The morphological analysis of crack propagation path and the contribution of nanoparticles were studied by observing process zone formation during crack propagation. A schematic model of nanoparticle distribution in injection molded specimens is also proposed based on fractographic analysis.
