Title
(EN) STRUCTURAL HOLLOW ARTICLES FILLED WITH DAMPING MATERIALS
(FR) ARTICLES DE CONSTRUCTION CREUX REMPLIS PAR DES MATERIAUX D'AMORTISSEMENT
Abstract
(EN)
The present invention provides a method of improving the vibrational damping characteristics of a structural material and the articles (1, 4) formed therefrom. The method involves: forming a cavity (2, 5) within the structural material at a point where at least one vibrational mode is active; and placing a nonconstrained vibration damping material (3, 6) into the cavity, wherein the vibration damping material comprises a viscoelastic material and preferably an effective amount of a fibrous material.
(FR)
L'invention concerne un procédé servant à améliorer les caractéristiques d'amortissement de vibrations d'un matériau de construction, ainsi que les articles (1, 4) obtenus au moyen dudit procédé. Ce procédé consiste à créer une cavité (2, 5) à l'intérieur du matériau au niveau d'un point sur lequel s'exerce au moins un type de vibrations et à placer dans ladite cavité un matériau d'amortissement (3, 6) non serré et composé d'un matériau viscoélastique, ainsi que, de préférence, d'une quantité efficace d'un matériau fibreux.
