本文介绍了对强度和密度有要求的拉伸PP/木纤维（WF）复合材料制成的人造木材的加工/结构/性能关系。PP/WF复合材料的拉伸使聚合物分子单向定向，沿拉伸方向的力学性能得到显著提高。复合材料的拉伸还通过在WF和聚合物基体界面产生空隙来降低人造木材的密度。确定了关键工艺参数和材料参数。研究了这些参数对结构和性能的影响。
This paper presents the processing/structure/property relationships for artificial wood made from stretched PP/wood-fiber (WF) composites that have required strength and density. The die drawing of PP/WF composites causesa unidirectional orientation of the polymer molecules and enhances the mechanical properties significantly along the stretched direction. The drawing of the composites also lowers the density of artificial wood by generating voids at the WF and polymer matrix interface. The critical processing and materials parameters are identified. The effects of these parameters on the structure and the properties are also investigated.
