A predictive model for heat flow during crystallization of semi-crystalline polymers

摘要: Crystallization plays an important role in polymer processes such as fiber spinning, injection molding and extrusion. The morphology of the crystalline phase ob tained influences mechanical physical properties material. energy or heat flow at liquid-solid interface during crystallization a key controlling kinetics subsequently influencing transforming However, formulating problem using Stefan's approach with constant temper ature is not sufficient for semi-crystalline matenals. In this paper, numerical taken to investigate influence kmetics, processing conditions varying thermo-physical on movement front. change crystallinity modeled by modifying temperature relating it overall cooling rate hypothetical control volume domain. results are compared analytical s...
