【摘要】 为进一步研究玻璃纤维/PVC复合材料的隔声性能,使其性能更加优越,以不同细度的玻璃纤维制成的织物和高阻尼的聚氯乙烯为原料,制备玻璃纤维织物/聚氯乙烯隔声复合材料,并采用双声道分析仪、SEM等对样品的隔声性能、形态结构进行分析测试。结果表明:玻璃纤维的细度对织物及复合材料的隔声性能都有较大的影响;在面密度、厚度等条件基本相同的情况下,玻璃纤维的直径越小,制成的织物及聚氯乙烯复合材料的隔声性能越好。更多还原

【Abstract】 In order to study the sound insulation of glass fabric/PVC composite material and improve its property,the glass fabric/PVC composites were manufactured from glass fibers with different diameters and PVC resin with high damp.The two-channel acoustic analyzer,SEM,etc were used to analyze the sound insulation property and micro-structure of the samples.The results showed that glass fiber′s fineness has great influence on the sound insulation property of both fabric and composite material.With the same density and thickness,the finer the glass fiber,the better the sound insulation of the fabric and composite material.更多还原
