玻璃纤维毡已经成为一种流行的降噪材料。采用火焰喷吹工艺生产玻璃纤维毡。研究了纤维分布、微观结构、渗透率和传声损失。结果表明，玻璃纤维毡的内部结构为无序结构，截面结构为微层结构。纤维直径与渗透速率之间存在直接的比例关系。对于复合材料结构，如果采用高反射系数的玻璃纤维毡面板，可以提高复合材料结构的STL。研究还发现，STL可以通过增加空气层的数量来改善。而对于STL，空气层位置变化的影响可以忽略不计。
Glass fiber felt has emerged as a popular material for noise reduction. In this paper, glass fiber felt is produced by flame blowing process. Fiber distribution, microstructure, permeation rate and sound transmission loss (STL) are explored. The results show that, the internal and cross-sectional structures of glass fiber felt are disordered and micro-layer, respectively. There is a directly proportional relationship between fiber diameter and permeation rate. For composite structure, if the face sheet of glass fiber felt with high reflection coefficient, STL of composite structure can be improved. It is also found that STL can be improved by increasing the number of air-layers. However, the influence of the position changing of air-layer can be ignored for STL.
