Vibration and noise have influence on the safety, comfort and tactical performance realization of naval ships. Application of damping material as an effective vibration and noise reduction measure has been widely applied in all kinds of ships, especially surface warships, for which the damping material can also improve ships＇ vitality. This paper introduces the mechanism of damping material for vibration and noise reduction, the factors affecting damping properties of materials, their categorization and damping effect evaluation method. Meanwhile, the general requirements on the damping material applied to surface vessels are proposed from the perspective of design. And the basic information and characteristic performance parameters of typical and widely-used damping materials both at home and abroad are introduced in combination with relevant standards. Besides the application requirements of damping material on the surface ships are put forward from the angle of construction. Damping material science is a kind of vibration absorption and noise reduction technology developed in recent years. With the development of high and new technologies, the requirements of damping materials are increasingly higher, which are developing towards the direction of wider temperature and wide frequency range and multiple functions. With the development of damping materials and its wide application on ships, the safety, comfort will be further improved and the tactical performance can be further ensured.
