Parameters Affecting the Damping Produced by a Septum-Loaded Fibrous Blanket 760659

A variety of parameters affecting the damping performance of a septum-loaded fibrous blanket were examined by extending the scope of the widely used “Geiger Thick Plate Test Method.”
Damping performance of a septum-loaded fibrous blanket system is influenced by the septum mass, the spacer layer material, and the manner in which the system is adhered. Increasing the septum mass improves the damping performance. By proper selection of the spacer layer and adhesion of the system, damping performance can be enhanced.
