摘　　要：研究了原纤化处理植物纤维对其多孔复合材料的结构性能和动态压缩性能的影响.利用超景深显微镜(SDFM)对植物纤维多孔复合材料结构特性,包括表面形貌和Z向纤维分布进行了表征.利用万能材料试验机(UMTM)对植物纤维多孔复合材料的动态压缩特性进行了测试.结果表明,利用原纤化处理后的植物纤维制备的多孔复合材料具有更均匀的孔隙结构,而且纤维在Z向分布更加均匀.原纤化处理后纤维之间的结合力增强,使得多孔材料更加密实化,结果导致应力-应变曲线中的平压区逐渐变短,密实化变形区域向低应变点偏移.In this study, the effect of the fibrillation of ptant fibers on the structure and dy-namic compression property of its porous composite material was investigated. The structure properties including surface morphology and fiber distribution along Z direction were studied by super depth of filed microscope （SDFM）. And the dynamic compression property of pro-duced porous composite material was tested by universal material testing machine （UMTM）. The results revealed that the pore structure and fiber distribution along Z direc-tion of the porous composite material made from the fibrillated plant fibers presented more uniform. In addition, the presence of more fines in the fibrillated fibers could increase the density of produced porous composite material by improving bonding strength between fiber and fiber,which resulted in the shorten of plateau curve and the shiftmen to lower strain percentage of densification curve in stress-strain curve.
