摘　　要：为充分发挥天然竹原纤维的可再生性和生物分解性,减少隔音复合材料对环境的负荷,并进一步改善竹原纤维/聚氨酯复合材料的隔音性能,以天然环保和可再生的竹原纤维为增强材料,以聚氨酯为基体,制备了一系列不同方式复合的隔音复合材料。研究了竹原纤维的排列方式与质量分数、及氢氧化钠溶液表面处理对复合材料隔音性能的影响。结果表明:竹原纤维采用直铺法制成的复合材料隔音性能最好;竹原纤维经氢氧化钠溶液处理后制成的复合材料其隔音性能显著提高;随着竹原纤维质量分数增加,复合材料的隔音性能增大。In order to give full play to renewability and biodegradability of nature bamboo fiber and reduce the environmental load of sound insulation composite material and further improve sound insulation performance of natural bamboo fiber/polyurethane composite material, a series of sound insulation composite materials were prepared in different ways using the natural environment-friendly and renewable bamboo fiber as the reinforcing material and polyurethane as base material. The influence of bamboo fiber packing modes, NaoH solution surface treatment and natural bamboo fiber content on the sound insulation composite materials was studied. The results showed that sound insulation performance of composite material with straight fibers packing is the best. Sound insulation performance is improved when fibers were treated by NaoH solution. With the natural bamboo fiber content increases, the sound insulation performance of composites increases.
