摘要
以玻璃纤维为原材料,设计出不同组织的正交和角联锁机织物,采用真空辅助模塑成型法将其加工成复合材料,然后用阻抗管-传递函数法测试其隔声性能,探讨纤维体积分数对隔声性能的影响。结果表明:材料隔声性能随着纤维体积分数的增加而增强,同时材料结构的完整性也影响其隔声性能。
Different orthogonal woven fabrics and angle-interlock woven fabrics have been fabricated by glass fi-ber, and composites was made through the vacuum-assisted molding（ VARTM） process system. The impedance tube-Transfer Function Method is used to test the sound insulation property of those composites,then the impression of fiber volume fraction on the sound insulation property is explored. The result shows that：the sound insulation property of wov-en composites have an increase trend with the increasing of its fiber volume fraction. At the same time,the integrity of composite structures have some part in the sound insulation.
