| 摘 要： | 通过挤出共混、造粒、注射成型的方式制备了黄麻纤维填充聚乳酸(PLA)复合材料,研究了复合材料的力学性能以及黄麻与PLA之间的微观界面形貌。结果表明:黄麻的加入,并没有很好地改善黄麻/PLA复合材料的拉伸强度和弯曲强度;碱处理后的黄麻与PLA之间的界面性能有所改善;碱处理黄麻的加入,改善了黄麻/PLA复合材料的断裂伸长率与冲击韧性。

| Abstract: | Jute fiber reinforced poly(lactic acid)(PLA) composites were prepared by extrusion blending and then injection molding. The mechanical properties and micro-morphology of interface between jute fiber and PLA matrix of composites were studied. The results show that the tensile strength and flexural strength are not improved after the addition of jute fiber. The interfacial adhesion of alkali treatment jute fiber reinforced PLA composites are improved, however, the elongation at break and the impact toughness of the jute fiber/PLA composites are improved. |
