Schwingungsdämpfender Werkstoff

摘要

In order to provide a damping material exhibiting an excellent vibration damping property over a wide temperature range, a magnetic composite type damping material is constructed by bonding an adhesive elastic sheet containing magnetic powder to a constraining plate such as a metal plate by using an adhesive, the adhesive elastic sheet is made of a composite material consisting of rubber elastomer, adhesive resin, plasticizer, magnetic powder, etc. The damping material having a construction described above not only holds an attracting force by magnetic force against a vibration source, but also is provided with a superficial adhesiveness. The excellent vibration damping property is exhibited over a wide temperature range of the synergistic effect of the magnetic force and the adhesion force.
