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.

Abstract: A material susceptible to dielectric heating has a base polymeric thermoplastic material (1) and a dielectric heating susceptor (2, 3) which increases susceptibility to heating by irradiation with electromagnetic, for example RF or microwave, radiation. The dielectric heating susceptor has a polymeric material (2) such as PVDF which is different from the base polymeric material and has a higher dielectric loss factor than the base polymeric material. The dielectric heating susceptor also comprises electrically polarisable entities such as carbon black dispersed within the base polymeric material without forming a conductive network. The two susceptor materials in combination with the base polymer are particularly effective together at improving susceptibility to electromagnetic radiation heating of the whole material.
