Morphology and Mechanical Property Relationship in Polypropylene Composites Conference Paper uri icon


  • Two high-crystallinity polypropylene (PP) based, inorganic filler-reinforced composites, i.e., PP/R-talc and PP/CaCO3 nanoparticles, were prepared and investigated. The mechanical properties of PP/R-talc and PP/CaCO3 composites were investigated using tensile test, flexural test, Izod impact test, and dynamic mechanical analysis. In addition, the morphology of the samples was studied by transmission electron microscopy and differential scanning calorimetry. Improvements of 150% and 30% in tensile moduli of PP/R-talc and PP/CaCO3 samples, respectively, can be attributed to the good filler particle dispersion and proper stress transfer between the matrix and mineral filler reinforcement.
