Abstract:
An article for damping vibrations by constrained layer damping comprising: a first constraining layer; a second constraining layer; and a damping layer disposed between the first and second constraining layers, wherein the first and second constraining layers each independently comprise a fibre-reinforced composite material, wherein the first and second constraining layers each independently have a thickness from 1.5 to 5 mm, wherein the damping layer comprises a viscoelastic material, wherein the damping layer has a thickness from 1 to 10 mm and wherein the article has a thickness from 6 to 50 mm. The invention also relates to the use of said article for damping vibrations in a vehicle.
