天然纤维复合降噪材料在汽车内饰中的应用

Application of Natural Fiber Composite Noise-reducing Material in Automobile Interior Decoration

介绍当前天然纤维复合降噪材料在汽车内饰中的应用状况。阐述了汽车噪声的来源与控制途径,分析了国内外汽车用天然复合降噪非织造材料的应用与发展状况,指出了我国车用降噪非织造材料的研究与国外先进水平尚有一定距离,在今后的研究中应更重视新原料、新工艺和新结构的研究,关注汽车用天然纤维复合降噪材料的便利性、经济性和舒适性。

Application of current natural fiber composite noise-reducing material in automobile interior decoration was introduced. Source and control way of automobile noise were introduced. Application and development situation of natural composite noise-reducing nonwoven material used in automobile at home and abroad were analyzed. It is pointed out there are certain distances comparing domestic noise-reducing nonwoven material used in automobile with the abroad in research field. Research in new raw material, new processing and new structure should be paid more attention from now on. Convenience, economical efficiency and comfort of natural fiber composite noise-reducing material used in automobile should be paid attention to as well.
