Double Scale Coupling Model of Plastic Injection Molding

Abstract:

The process of short fiber reinforced injection molding is a typical multi-scale problem, it has become a cutting-edge issue of the field of polymer molding to study clearly the mesoscopic structure changing rules in the whole molding processing. Aiming at the processing of glass fiber reinforced polypropylene injection, basing on the foundation of macro continuum medium model, approximated short fiber reinforced injection molding process as macro-mesoscopic double scale problem composed by macro-flow and small-scale short fiber movement, establish the double scale model, which couple Mesoscopic fiber orientation. And the cooling crystallization model was established by learning from multi-scale simulation of liquid metal crystallization method.
