Title (EN) CONSTRAINED LAYER, COMPOSITE, ACOUSTIC DAMPING MATERIAL
(FR) MATIERE COMPOSITE D'AMORTISSEMENT ACOUSTIQUE A COUCHE CONTRAINTE
Abstract: front page image
(EN)A constrained layer, composite structure for damping acoustic vibrations includes an extensional layer comprised of a first polymeric material, and a constraining layer of a second polymeric material. The modulus of elasticity of the constraining layer is greater than that of the extensional layer. In use, the structure is disposed on the surface of an article in which acoustic vibrations are to be damped so that the extension layer overlies the surface. Also disclosed are methods for preparing the structure, including automated methods.
(FR)La présente invention concerne une structure composite à couche contrainte qui sert à amortir des vibrations acoustiques et comprend une couche d'extension faite d'une première matière polymère, et une couche de contrainte faite d'une seconde matière polymère. Le module d'élasticité de la couche de contrainte, est supérieur à celui de la couche d'extension. En cours d'utilisation, la structure est disposée à la surface d'un article dans lequel les vibrations acoustiques doivent être amorties de sorte que la couche d'extension recouvre la surface. L'invention a également pour objet des procédés pour préparer la structure, comprenant des procédés automatisés.
