Abstract

A vibration absorbing material preferably includes a first elastomeric layer of vibration absorbing material which is substantially free of voids therein. A second layer including a hight tensile fibrous material and that is disposed on the first elastomeric layer. The high tensile strength fibrous material distributes vibration to facilitate vibration dampening. A third elastomeric layer is disposed on the second elastomeric layer.
