Review of Laminated Steel Plate for Vibration Damping

Abstract

This paper is concerned with the properties of sandwiched type laminated steel plate which excels at vibration damping. The laminated steel plate is prepared by sandwiching a viscoelastic resin sheet between two steel plates and leads to the vibration damping. Sufficient weldability and formability are required for the application to structural materials. However, the laminated steel plate is isolated by the resin, and has poor weldability. Furthermore, unfavourable phenomena, such as peeling and wrinkle, occasionally arise in this plate. In spite of the fact that such problems have been not completely solved yet, this plate has been applied as damping materials in automobile, electrical and architectural industries. The market of this plate will certainly expand in future.
