摘要
选用未处理及处理的竹纤维、麻纤维和椰子纤维增强环氧复合材料,通过试验,评估了纤维质量分数从0增加至20%时复合材料的声学性能变化。试验结果显示,随着植物纤维质量分数的增加,复合材料的声传播速度和声反射系数降低,而声衰减系数和声吸收系数则有所提升。这表明植物纤维的引入及其表面处理显著改善了环氧复合材料的吸声性能,为声学材料的设计提供了新的视角和数据支持。
The acoustic properties of epoxy composites reinforced with untreated or treated bamboo fiber,hemp fiber and coconut fiber were evaluated by experiments when the fiber mass fraction increased from 0 to 20%.The results show that with the increase of plant fiber mass fraction,the acoustic propagation velocity and acoustic reflection coefficient of the composites decrease,while the acoustic attenuation coefficient and acoustic absorption coefficient increase.This shows that the introduction of plant fiber and its surface treatment significantly improve the sound absorption properties of epoxy composite,providing a new perspective and data support for the design of acoustic materials.
