摘    要:利用自行设计制造的剪切拉伸双向复合应力场挤管装置生产出了短玻璃纤维/高密度聚乙烯/聚丙烯(SGF/HDPE/PP)双向增强管材。采用大角X射线衍射法(WAXRD)和扫描电镜(SEM)研究分析了SGF/HDPE/PP双向增强管材内的玻璃纤维和聚合物分子的取向分布。结果表明,在剪切拉伸双向复合应力场的诱导下,SGF/HDPE/PP双向增强管材内的玻璃纤维已形成了同时沿管材的轴向和周向的双向取向分布;增强管材内部的聚合物分子已被明显地拉长变形,并在沿135°角的方向上获得了较好的取向分布,因而可同时改善管材的轴周向性能。

关 键 词:双向应力场  挤管模  SGF/HDPE/PP管材  诱导  取向

Abstract:By shearing-drawing two-dimensional compound stress field die developed by the authors,two-dimensional reinforcement short glass fiber/high density polyethylene/polypropylene(SGF/HDPE/PP) pipes were extruded.The orientation behaviors of glass fiber and polymer molecule of these pipes were studied by wide-angle X-ray diffraction(WAXRD) and scanning electron microscope(SEM) in this paper.The results indicate that due to the inducement of the shearing-drawing two-dimensional compound stress field,the glass fib...
Keywords:two-dimensional compound stress field  pipe extrusion die  SGF/HDPE/PP pipe  inducement  orientation
