| 摘 要： | 为了达到水下声隐身的目的,必须对水声吸声材料进行研究。聚氨酯弹性体材料因其独特的分子结构和可设计性得到广泛应用。考虑用其作为水声吸声材料,但该材料的合成工艺影响因素很多,进行合理的工艺设计可以大大减少试验量。本文从聚氨酯弹性体的微相分离和微观阻尼吸声机理出发,研究设计了聚氨酯弹性体水声吸声材料的合成工艺,并根据该工艺参数制作了聚氨酯弹体声学测试试样,在脉冲声管中测试了试样的吸声系数,测试结果表明所设计的工艺参数是合理的。

| Abstract: | Underwater anechoic material must research for the aim of underwater sound stealth. Polyurethane elastomers material has been extensively applied because of their unique molecular structures and desirable. The effect factors of synthetical technology on this material are numerous. So,the number of experiment will reduce largely by reasonable synthetical technology design. The microphase separation and microcosmic sound absorption mechanism of polyurethane elastomers were analyzed. The synthetical technology... |
