た使用できず、使用個所が限定されると言う問題があっ
た。By the way, in order for a sheet-shaped damping material to exhibit damping characteristics, it is required to have a thickness that is 1 to 3 times the thickness of the damped member (object). In the case of objects, there is a problem in that they become heavy, and when used above room temperature, the rigidity of the damping material, which is mainly composed of thermoplastic resin, increases, making it difficult to follow the complex shape and irregularities of the damped member. This poses a problem in that it cannot be used at temperatures below room temperature, and the locations where it can be used are limited.
