Abstract
In order to provide a damping material exhibiting an excellent vibration damping property in a wide temperature range, according to the present invention, in a magnetic composite type damping material 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. Since not only is the damping material having a construction described above attracted by magnetic force against a vibration source, it also is provided with a superficial adhesiveness, and the excellent vibration damping property is exhibited in a wide temperature range by a synergistic effect of the magnetic force and the adhering force.
