This paper reviews the state-of-the-art progress in the multiscale modeling and simulation of injection molding of polymer blends, discussing technological development on a macroscale and various models for morphology evolution on a mesoscale. Strategies for scale-bridging between mold-filling flow and morphology evolution are analyzed and compared, presenting a comprehensive summary and outlook for future research in this field.
Modeling and simulation of the morphology evolution of immiscible polymer blends during injection molding is crucial for predicting and tailoring the products' performance. This paper reviews the state-of-the-art progress in the multiscale modeling and simulation of injection molding of polymer blends. Technological development of the injection molding simulation on a macroscale was surveyed in detail. The aspects of various models for morphology evolution on a mesoscale during injection molding were discussed. The current scale-bridging strategies between macroscopic mold-filling flow and mesoscopic morphology evolution, as well as the pros and cons of the solutions, were analyzed and compared. Finally, a comprehensive summary of the above models is presented, along with the outlook for future research in this field.
