摘　　要：在动态保压剪切力场及高分子量聚乙烯线形成核的诱导下制备了性能良好的聚乙烯复合物,本次实验证实了HMW PE的诱导作用,考察了拉伸试样的应力应变行为,发现了断裂方式的转变,而SEM照片中网状串晶这一特殊结构也得到了合理的解释。The good performances of HDPE/HMWPE composites were Obtained under powerful shearing field of dynamic packing injection molding （DPIM） technology and the inducement of HMWPE chains. The inducement of HMWPE was confirmed, stress-strain behavior was surveyed in this experiment. We found the change of fracture mode, and the reasonable explanation was given according to special structure-web like shish-kebabs from the SEM photos.
