摘要
本文研究了以植物纤维与聚乳酸为原料制备生物质复合材料的工艺,探讨不同加工方式、纤维种类和添加量对植物纤维/聚乳酸复合材料拉伸性能及透湿性的影响,并利用扫描电镜对复合材料进行表征。研究结果表明:复合材料采用熔融挤出加工方式比物理混合的性能好,而蔗渣纤维作为填料是较好的选择;同时,当植物纤维添加量低于20%时,随着添加量的增加,材料的拉伸强度和断裂伸长率随之下降。
The process of the biomass composites prepared with plant fiber and polylactic acid was studied in this paper. The effects of various processing methods, fiber type and fiber content on ten- sile properties and water vapor transmission of the biomass composites were discussed. The proper- ties of composite was characterized by scanning electron microscopy （SEM）. The results showed that melt extrusion technique is better than physical mix; bagasse fiber is the best filler among the tested plant fibers. When fiber content was less than 20% , the tensile strength and elongation at break of the composites was decreased with the increase of fiber.
