LAMINATE DAMPING BASE MATERIAL, AND DAMPING STRUCTURE WITH STACK OF THIS BASE MATERIAL

摘要

.A damping structure which dispenses of the connection of a resistor used for a conventional damping structure and undergoes diverse molding processings with a simpler structure,and a laminate damping base material constituting such a damping structure.A laminate damping base material made of a piezoelectric ceramic material or piezoelectric high−polymer material and a conductive fiber−reinforced plastic(FRP)composition is prepared.One to a plurality of this base material are stacked to constitute a first damping structure.A second damping structure is constituted by stacking at least a layer of piezoelectric high−polymer film or piezoelectric ceramic thin film between a multilayer laminate that is a laminate of conductive laminate FRP base materials.
