    Abstract: PURPOSE:A vibration damping material having high strength, excellent water resistance, chemical resistance, and an improved vibration damping effect and capable of being bonded also to a part of a complicated shape, prepared by adding a fibrous material to a composition formed by mixing an epoxy resin with a curing agent and a particulate iron oxide. CONSTITUTION:A vibration damping material prepared by adding 0.5-50pts.wt. fibrous material (e.g., polyethylene synthetic pulp) to a composition prepared by adding 40-900pts.wt. particulate iron oxide (e.g., Fe3O4 of an average particle diameter of 1mu) to 100pts.wt. mixture of an epoxy resin (e.g., liquid bisphenol A- derived epoxy resin) and a curing agent (e.g., polyamidoamine). This vibration damping material exhibits an excellent vibration damping effect because its cured product has a high vibration damping factor and a large specific gravity. This vibration damping material provides good workability, can be applied to a part of a complicated shape, is excellent in water resistance and chemical resistance, and can be applied to a wide area. This material is excellent in adhesiveness and bondable to bases such as metal, wood, and FRP.

    Abstract: PURPOSE:To obtain a good vibroisolation effect with a simple constitution by attaching a piezoelectric element to a vibroisolated body which is subject to the vibroisolation and vibratorily exciting the vibroisolated body by means of the piezoelectric effect of the piezoelectric element. CONSTITUTION:A beam structure 1 is attached with a piezoelectric element 6 which vibratorily excites the beam structure 1 and a vibration pick-up 2 to measure the vibration of the beam structure 1. The detected signal by the vibration pick-up 2 goes through an amplifier 3 to be fed to a signal converting circuit 4 where it is converted to a phase that damps the vibration of the beam structure 1. Such signal then is sent to the piezoelectric element 6 via an amplifier 5. The piezoelectric element 6 vibratorily excites the beam structure 1 by its piezoelectric effect with a phase that damps the vibration, and so, the vibroisolating effect of the beam structure 1 can be obtained.
