声纳罩是保证声纳站在水中处于良好工作环境的透声壳体,同时也是船体结构的一部分。做为声纳罩的壳体材料,不但要具有良好的透声性能,而且还要具有足够的强度、刚度以及耐海水老化等性能。 六十年代,声纳导流罩材料尚采用1.5～2mm厚的不锈钢,由于它透声效率低、重量大、成本高、安装困难,不能满足声纳站日益发展的需要,为此,我所开展了玻璃纤维增强塑料
Sonar covers are soundproof enclosures that ensure the sonar station is in good working condition in the water and are also part of the hull structure. As a shell material sonar cover, not only have good sound permeability, but also have sufficient strength, stiffness and resistance to sea water aging and other properties. In the 1960s, the sonar shroud material still used 1.5 ~ 2mm thick stainless steel, because of its low sound transmission efficiency, weight, high cost, difficult to install, can not meet the growing needs of sonar station, for which I Launched a glass fiber reinforced plastic
