摘要/Abstract

摘要： 以亚麻纤维为原料,聚丙烯为基体,制备纤维含量分别为0%、10%、20%、30%、40%的纤维增强复合材料,并对亚麻纤维进行碱处理和偶联剂处理,探讨了纤维含量以及表面处理对亚麻纤维增强复合材料的隔声性的影响。研究结果表明,当纤维含量超过10%时,复合材料的隔声性随着发声频率增加出现先增大后减小的趋势,同一发声频率,含量越低,隔声性能越差,当纤维含量超过30%后,电压峰值衰减率反而下降;表面处理后,复合材料的隔声性能有所提高,偶联剂处理后复合材料的隔声性能优于碱处理后的复合材料。

Abstract: The polypropylene composites reinforced by flax fiber with the content of 0%, 10%, 20%, 30%, and 40% were prepared. Also the flax fiber modified by alkali and silane coupling agent KH -570 reinforced composites were prepared, and effects of fiber content and surface modification by alkali and silane coupling agent KH-570 on the acoustic properties of composites were studied. The results showed that the acoustic property of composite first increased and then decreased with the trend of increasing audible frequency when the fiber content overpass 10%. When the audible frequency was the same, the lower the content of the flax fiber, the worse the acoustic performance. But, when the content of the flax fiber overpass 30%, the peak voltage attenuation percentage declined. After surface treatment, the acoustic properties of composites were enhanced, and the flax fiber treated with coupling agent reinforced composites was better than that treated with alkali reinforced composites.

Key words: flax fiber, polypropylene, content, treatment, acoustic property
