の問題がある。However, when a thermoplastic resin is used, for example, in an engine oil pan, when it is continuously used at a temperature of 130 ° C. or higher, or when it is placed in a high temperature environment such as baking coating, the adhesive strength is increased. Also, there is a problem that the loss coefficient is lowered, and if the resin is softened and bolted, the bolt loosens due to torque reduction. In addition, in the degreasing process before baking coating, there are problems that the degreasing liquid permeates from the end portion and that it swells with oil.

性能を満足する制振複合鋼板が強く望まれている。Therefore, although a vibration-damping composite steel sheet is produced which uses a thermosetting resin which is excellent in heat resistance, oil resistance and degreasing liquid resistance, and which does not soften at high temperatures, this vibration-damping composite steel sheet. Is inferior to thermoplastic resin in that it causes peeling of the vertical wall during press bending. Therefore, a vibration-damping composite steel sheet satisfying the excellent performances of both of these thermoplastic resins and thermosetting resins is strongly desired.

The thickness of the resin layer is not particularly limited, but is preferably in the range of 0.01 mm to 0.5 mm. If the thickness is less than 0.01 mm, the vibration damping property is low, and if it exceeds 0.5 mm, the weldability is deteriorated.
