摘　　要：隔音阻尼复合材料作为汽车隔音的重要材料之一,被广泛应用。某型号热熔隔音阻尼复合材料的基体和增强相组成的相互影响,此材料在车身烘烤后发生翻边品质不良,通过改变增强相的维排布的结构和材料轻量化等工艺实验改善方法,达到增加附着力杜绝翻边不良的目的,隔音阻尼复合材料未来避免不了增强相多元化发展、涂布状态改变等的发展趋势。As one of the important materials for automotive sound insulation,soundproofing and damping composite materials are widely used.The mutual influence of the matrix and reinforcement phase composition of a certain type of hot melt soundproof damping composite material results in poor flanging quality after the vehicle body is baked.By changing the structure of the reinforcement phase arrangement and improving the material's lightweight process,the aim is to increase adhesion and eliminate flanging defects.In the future,soundproof damping composite materials cannot avoid the trend of diversified development of reinforcement phases and changes in coating status.
