Abstract：On the basis of the former research works, this paper researched emphatically onthe induced crystallization of boundary stress of HDPE based composites and the relationships ofthe induced crystallization and the properties of materials, and gave a detailed discussion on the re-lations of boundary binding,CaCO₃particle size, particle size distribution, content and cooling rateof sample, etc and the induced crystallization of the base and the toughness of the composite.Therelevant toughenment mechanism, toughenment model and the experimental results of crystallinekinetics were introduced.
