摘　　要：以竹纤维、聚丙烯纤维为原料,采用热压成型工艺制作竹纤维增强聚丙烯基复合材料(竹纤维/PP),研究制作结构和碱处理对竹纤维/PP吸湿性能的影响.研究表明:竹纤维/PP吸湿规律符合Fick吸湿定律;结构优化和碱处理均改善了竹纤维/PP界面性能,降低了其吸湿性能.Bamboo fibers reinforced polypropylene composites were prepared by means of moulding pressing technology. The effects of structure and alkali treatment of bamboo fibers on the hygrothermal properties of the composites were discussed respectively. The results reveal that the moisture absorption behavior of bamboo/PP is conform to Fick law. After structure optimization and alkali treatment, the interfacial property and hygrothermal property of bamboo/PP get some improvement.
