US 7,337,981 B2 · Vibration damping system

Abstract

The invention relates to a vibration damping system, which comprises an anti-vibration plate in the form of a plate having a first and a second major surface, wherein the first major surface may preferably be covered with a layer of surfactant-free geotextile. The anti-vibration plate comprises one or more layers, preferably a top layer and one or more bottom layers. Furthermore, it is essential that the anti-vibration plate is preferably obtainable by a method comprising the step of subjecting an area of the opposite surfaces of the plate to a compression treatment in one or more steps, which compression treatment is sufficient to reduce the static and/or the dynamic stiffness of the plate compared to the static and/or dynamic stiffness prior to the compression. The invention also relates to the method of applying a vibration damping system and the use of a vibration damping system.

Dependent claims

A method of making an anti-vibration plate for a vibration damping system, comprising the steps of:

a) providing a plate having a first major surface and an opposite second major surface, said plate comprising one or more layers comprising mineral fibres and a cured binder, and
b) compressing an area of said opposite first and second major surfaces of said plate provided in step (a) to reduce the static and/or dynamic stiffness of the plate by at least 10% compared to a static and/or the dynamic stiffness of said plate prior to step (b), said plate provided in step a) comprising two of said layers comprising mineral fibers and cured binder, one of said layers defining a top layer and the other defining a bottom layer, said top layer defining said first major surface and said bottom layer defining said second major surface, said top layer and said bottom layers having different densities.
