Impact resistance of hetero-phase polymericmaterials

摘要

Hetero-phase polymeric materials, such as high-impact polystyrene (hiPS) and impactpolypropylene (iPP), have many applications because of their excellent impactresistance. The methodology of discrete element method (DEM) is adopted fornumerical simulations of hetero-phase polymer particles hitting the solid wall.Systematic mapping from the parametric space of polymer morphologies to theparametric space of impact-resistance properties was carried out. Distribution ofrubbery domains in polymeric materials strongly affects their impact resistance.
