Abstract

Impact-modified polypropylene, which is a blend of polypropylene with an impact modifier such as ethylene propylene rubber, ethylene/alpha-olefin elastomers or styrenic-based rubber, is commonly used for applications with impact resistant requirements. In addition to the shape, amount and size distribution of rubber particles, crazes give additional deformation after elastic deformation until the necking process. In this study, a quantitative modeling of tensile behavior of impact modified polypropylene based on a micromechanical model of crazing initiated from rubber particles is presented. An accurate prediction of the stress-strain relationship until necking is possible based on the proposed model.
