纤维基发泡涂层吸声复合材料的制备及性能
Preparation and performance of fiber-based foam-coated sound absorption composite material
摘要
Abstract
To address the poor sound absorption performance of lightweight fiber materials,this study developed fi-ber-based foam-coated sound absorption composite materials with varying foaming rates,coating thicknesses,foaming agents,and activated carbon content through mechanical foaming and coating processes.The research evaluated their sound absorption,noise reduction,and breathability characteristics.The results demonstrated that foaming rate,coating thickness,foaming agent selection,and activated carbon addition significantly influenced material properties.The foam-coated com-posite exhibited enhanced sound absorption performance,with performance improvement showing an increasing trend as foaming rate decreased and coating thickness increased.At 100％foaming rate with 1 mm coating thickness,the material achieved a maximum sound absorption coefficient of 0.833 across tested frequency ranges,while its average sound absorp-tion coefficient and noise reduction efficiency were 2.75 times and 3.4 times higher than those of wool felt,respectively.关键词
