An effective film construction was provided as a noise‐reducing materials based on self‐assembled polymer film supported by ultralight glass fiber blanket (UGFB) skeleton. The synthesized polymer film enhanced UGFB structure shows about 60% improvement over a broad frequencies compared to neat UGFB. The sound transmission loss has a remarkably increasing of 16.59 dB at 4 kHz. The reinforced acoustic performances was created by the structural optimization of UGFB/UMPR‐film, owing to the observably enhanced tortuosity in sound waves transmission and reinforced surface area, which can induce more viscous and thermal losses when the acoustic wave consumes in the semiopen pore construction. Moreover, the UGFB/UMPR‐film demonstrates 7.4 times increasing in breaking strength (width direction) and the degrees of uniformity lower than 0.0771. The manufacture of this new acoustic damping materials is low cost, structural controllable, and easy to large‐scale preparation, making it can be applied in multitudinous applications.

玻璃纤维间交叉膜对橡皮布性能的影响

基于超轻玻璃纤维毯（UGFB）骨架支撑的自组装聚合物薄膜，提供了一种有效的薄膜结构作为降噪材料。与纯的UGFB相比，合成的聚合物薄膜增强的UGFB结构在较宽的频率上显示出约60％的改善。在4 kHz时，声音传输损耗显着增加了16.59 dB。增强的声学性能是通过UGFB / UMPR薄膜的结构优化而产生的，这是由于声波传输中的曲折性明显增强，表面积得到了增强，当声波在半开孔结构中消耗时，会引起更多的粘性和热损失。此外，UGFB / UMPR膜的断裂强度（宽度方向）提高了7.4倍，均匀度低于0.0771。
