| 摘 要： | 为了探讨整体中空复合材料结构与隔声性能之间的关系, 设计并制备了不同高度、不同面板厚度以及不同芯材的玻璃纤维整体中空织物/环氧树脂复合材料。采用混响室-消声室法对其隔声性能进行了测试分析。研究表明: 整体中空复合材料的结构对其隔声性能有明显的影响。复合材料的隔声性能随着结构高度的增加逐渐提高, 面板厚度对材料的隔声效果影响较大, 芯材排列形式对其隔声性能影响相对较小; 8 形整体中空复合材料的隔声性能略高于 88 形和 X 形。

| Abstract: | In order to study the relationship between the composite structure and sound insulation property of integrated hollow core sandwich composites,the glass fabric/epoxy resin composites with different heights,panel thicknesses and core structures were fabricated.The experiments for sound insulation property were carried out in a reverberation-anechoic chambers measuring system.The results show that the structure of glass fabric has an obvious influence on the sound insulation property of integrated hollow core... |
