６巻、第２９１ 号、 ３９４〜３８９頁）。BACKGROUND OF THE INVENTION In recent years, noise caused by automobiles has become a social problem. In addition, from the viewpoint of comfort inside the vehicle, there is a need for noise countermeasures, especially in diesel vehicles. In particular, as a measure to reduce vibrations around engines, vibration-damping steel plates in which viscoelastic resin is used as a damping material and are laminated in a Santoy-Sochi shape between two steel plates are beginning to attract attention (Plasticity and Processing, Vol. 2).

曲げ剛性は全厚が同一の冷延鋼板と較べ著しく低下する
。このため、制振鋼板で冷延鋼板と同一の剛性を確保す
るためには全厚を増す、すなわち鋼板の使用量を増加さ
せなければならず、重量増加となる。However, the damping steel plate has a structure in which a thin soft viscoelastic resin of about 0.051 m is sandwiched between thick steel plates of about 0.4 to 0.8 mm, and when the damping steel plate vibrates,
The resin layer absorbs energy by causing shear plastic deformation and exhibits vibration damping properties.Conversely, since shear deformation occurs with a small force between the skin steel plates, its bending rigidity is The total thickness is significantly lower than that of a cold-rolled steel sheet with the same thickness. Therefore, in order to ensure the same rigidity as a cold-rolled steel plate with a damping steel plate, the total thickness must be increased, that is, the amount of steel plate used must be increased, resulting in an increase in weight.
このような重量増加をまね〈制振鋼板は、それが構造部

るコストアップ、自動車などでは燃費の上昇をまねき、
省エネルギー、省コストが重視される社会状勢に対して
かならずしも有利な方向ではない。To imitate this increase in weight, damping steel plates, when used as structural members, are heavy themselves, and at the same time the rigidity of the members supporting them must also be improved, resulting in an increase in the weight of the entire structure, In addition, the increase in the amount of steel used leads to increased costs and increased fuel consumption in automobiles, etc.
This is not necessarily an advantageous direction given the social situation where energy and cost savings are emphasized.
この意味から、軽量でかつ、制振性能の高い材料が真に
待望されており、自動車以外の分野、例えば、びびり音

が高い。In this sense, there is a real need for materials that are lightweight and have high vibration damping performance, and are also in high demand in fields other than automobiles, such as home appliances, furniture, and building materials that require the reduction of chatter and impact noise. .

形を生じないため、上記制振鋼板におけるメカニズムで
は制振性を生じない。A laminated metal plate is a laminate of steel plate-resin-steel plate in which an elastic resin (core material) such as nylon-6 or polypropylene is sandwiched between two metal plates (skin metal plate).The skin and core material resist external forces. It deforms as a unit, and there is no shear deformation between the skin and the core material like with damping steel plates. Therefore, the bending rigidity is almost the same as that of the metal plate with the same overall thickness, and the center Since the specific gravity of the resin layer is about 1/8 from 173 to that of the metal plate, it is possible to reduce the weight by several tens of percent. However, in terms of damping properties, the resin layer does not undergo plastic deformation due to shearing, so the mechanism in the damping steel plate does not produce damping properties.
