短亚麻纤维/聚乳酸复合材料制备与性能研究OA北大核心CSTPCD
Study on Preparation and Properties of Short Flax Fiber/PLA Composite
采用双螺杆挤出机制备出一系列短亚麻纤维/聚乳酸复合材料,通过力学性能测试、SEM和DSC等方法研究了短亚麻纤维用量、偶联剂种类对短亚麻纤维/聚乳酸复合材料力学性能、结晶性能、流变性能和耐热性能的影响.结果表明:短亚麻纤维用量达到4.62%时,亚麻纤维/聚乳酸复合材料力学性能达到最佳;随短亚麻纤维用量的增加,亚麻纤维/聚乳酸复合材料流动性降低,而结晶度和耐热性有所提高.
A series of short flax fiber/PLA composites were prepared by twin-screw extruder. The effects of content of short flax flber and type of coupling agent on mechanical, rheological and crystallization properties were studied respectively by means of mechanical property test, SEM, DSC and so on. The results show that when short flax fiber content is 4.62％, the mechanical property of short flax fiber/PLA composite is the best; with the increase of short flax fib…查看全部>>
