摘　　要：为达到部分替换黄麻吸声材料的目的,研究了棕榈木棉纤维毡/聚3-羟基丁酸-戊酸酯(PHBV)热压复合材料的吸声性能及影响因素。分析了棕榈纤维、木棉纤维、PHBV质量比,纤维毡面密度,棕榈纤维线密度,吸声复合材料厚度对该热压复合材料低频(200 Hz~1600 Hz)吸声系数平均值的影响。结果表明:采用2块纤维毡且棕榈、木棉、PHBV的质量比为10∶30∶60,纤维毡面密度分别为185 g/m^(2)、145 g/m^(2),木棉纤维线密度为0.25 tex,棕榈纤维线密度为0.60 tex,热压复合材料厚度为4 mm时,所制备吸声材料的低频吸声系数平均值达0.42,可以作为吸声材料投入实际生产。In order to partially replace jute sound absorption material,sound absorption performance and influencing factors of the palm kapok fiber felt/poly(3 hydroxybutyrate-valerate(PHBV))hot pressed composite material were studied.The effcts of palm fiber,kapok fiber and PHBV mass ratio,fiber felt surface density,palm fiber linear density,the thickness of the composite material on the average sound absorption coefficient at low frequency(200 Hz~1600 Hz)were analyzed.The results showed that the 2 pieces of fiber felt was adopted and the mass ratio of palm,kapok,PHBV was 10∶30∶60,surface density of the fiber felt was 185 g/m^(2) and 145 g/m^(2) respectively,linear density of kapok fiber was 0.25 tex,linear density of palm fiber was 0.60 tex,thickness of hot pressed composite materials was 4 mm,the average low frequency sound absorption coefficient of hot pressed composite material was 0.42,which could be used as absorption material in actual operation.
