摘要
水声吸声材料常用于水下航行体表面,其研究对于水下目标的声隐身设计具有重要意义,在军事应用领域受到广泛关注。橡胶类和聚氨酯类粘弹性高分子材料因其独特的分子结构和可设计性得到广泛应用,此外吸声材料的结构设计对其性能也有着很大影响。本文在水声吸声材料吸声机理的基础上,对其主要材料体系和吸声结构进行了综述。
Acoustic sound absorption materials are commonly used in the underwater navigation surfaces. The underwater acoustic stealth design is of great significance in the military applications and gets extensive attention. Polymeric materials like rubber and polyurethane have been extensively applied because of their unique molecular structures. The structural design of sound-absorbing material also has great affection on their performances. In this paper, the main systems and sound absorption material structures were reviewed on the basis of the acoustic absorption mechanisms.
