摘  要：
利用聚合物发泡技术和木质人造板复合工艺制备木质纤维/聚酯纤维复合吸声材料,并研究复合工艺条件对该材料力学性能及吸声性能的影响。结果表明:将胶黏剂和发泡剂加入木质纤维及聚酯纤维中进行复合是可行的;较佳复合工艺为热压温度150℃,加压时间10 min;在一定温度范围内,随着时间的延长,材料力学性能有所提高,声学性能变化不大;在一定时间范围内,随着温度的升高,材料的力学性能和声学性能都有所提高。频率为1600~4 000 Hz范围内,在140℃条件下材料平均吸声系数为0.65,而150℃条件下为0.7。

摘  要：
Polymer foaming technology and wood-based composite technology are used for producing sound-absorbing composite materials using wood fiber and polyester fiber as the raw materials in this paper,and the effects of the preparing conditions on the mechanical properties and sound-absorbing performance of the composite were investigated. The results show that it is feasible to add the adhesive and a foaming agent into wood fibers and polyester fibers to make a composite material,and the optimum conditions were determined as follows: hot pressing temperature 150 ℃ and composite time is 10 min. In a certain temperature range,the mechanical properties are improved along with time increasing,while the time has little effect on the acoustic performance. And in a certain time range,as the temperature increases,both the mechanical properties and acoustic performance improved. The average absorption coefficient of the material is 0. 65 at the temperature 140 ℃ in the range from 1 600 Hz to 4 000 Hz,while it is 0. 7 at 150 ℃.
