    Patent number: 4942080
    Abstract: To extend the temperature range of composite materials the composite material is made up of more than two hard layers which are joined with thin intermediate layers of viscoelastic material where one intermediate layer differs from another intermediate layer in that its softening range lies in a different temperature range so that the damping ranges of the intermediate layers also are different.
