Abstract:
A passive damping mechanism for a panel member in which a bonding layer is disposed on each side of the panel, a damping layer is disposed on each of the two bonding layers, and a constraining layer is disposed on each of the two damping layers. Each of the above-mentioned layers is coextensive with the respective panel surfaces to which it is attached. The bonding layers are preferably made of an aramid fiber material. The damping layers are preferably made of a viscoelastic material. The constraining layers are preferably made of an aluminum-graphite metal matrix composite material. In addition, the coefficient of thermal expansion of each bonding layer should match well with that of each constraining layer.
