Impact fracture behavior of PP/EPR blends Conference Paper

abstract

• The impact fracture behaviors of two commercial polypropylene/ethylene- propylene rubber (PP/EPR) blends were investigated. The morphology and interfacial characteristics were directly characterized by transmission electron microscopy. The effects of EPR composition on phase morphology, interface and impact fracture behavior were systematically studied. The toughening mechanisms were examined using the double-notch four-point-bending technique. It is found that crazing and shear banding are the two dominant energy dissipation mechanisms in the impact PP/EPR blends investigated. Possible approaches for optimizing the impact strength of PP/EPR blends are also discussed.
