| 目的 以工业大麻纤维和聚乳酸纤维为原料，通过湿法制备工业大麻/聚乳酸纤维复合材料，并探究其力学性能和吸声性能。方法 利用非织造和热压工艺湿法制备得到不同质量比(8∶2、7∶3、6∶4、5∶5)的工业大麻纤维/聚乳酸纤维复合材料，对材料进行结构及性能测试，探究聚乳酸纤维对工业大麻纤维的力学性能和吸声性能的影响。结果 随着聚乳酸纤维比例的增加，材料力学性能逐渐增强。其中，质量比为5∶5的材料的力学性能最好;聚乳酸纤维越多，材料的吸声系数越低，质量比为8∶2的材料的吸声性能最好。结论 工业大麻/聚乳酸纤维复合材料具有良好的吸声性能和力学性能。 |

| The work aims to prepare industrial hemp/polylactic acid fiber composites by wet method with industrial hemp fiber (PLA) and polylactic acid fiber (HF) as raw materials, and explore the mechanical properties and sound absorption properties of the composites. Industrial hemp fiber/polylactic acid fiber composites with different mass ratios (8∶2, 7∶3, 6∶4, 5∶5) were prepared by non-woven and hot pressing wet method. The structure and properties of the materials were tested to explore the effects of polylactic acid fiber on the mechanical properties and sound absorption properties of industrial hemp fiber. With the increase of the mass ratio of polylactic acid fiber, the mechanical properties of the material were gradually enhanced. Among them, the mass ratio of 5∶5 resulted the best mechanical properties. The more polylactic acid fiber, the lower the sound absorption coefficient of the material, and the mass ratio of 8∶2 resulted the best sound absorption property. Industrial hemp/polylactic acid fiber composites have good sound absorption and mechanical properties. |
