Title
(EN) SILICA-CONTAINING VIBRATION DAMPER AND METHOD
(FR) AMORTISSEUR DE VIBRATIONS CONTENANT DE LA SILICE ET PROCEDE ASSOCIE
Abstract
(EN)
A method for vibrationally damping an article that is subject to resonant vibrations comprises the steps of providing a vibration damper and applying the vibration damper to the article to damp the resonant vibrations. The vibration damper comprises an acrylate viscoelastic vibration damping material and an effective amount of hydrophobic silica. The invention also relates to vibration dampers that utilize the acrylate viscoelastic vibration damping material as well as articles that incorporate the vibration dampers.

Procédé d'amortissement des vibrations induites à un élément soumis à des vibrations résonnantes. Le procédé consiste en un amortisseur de vibrations qui est appliqué sur l'élément dont les vibrations résonnantes doivent être amorties. L'amortisseur de vibrations renferme un matériau d'amortissement de vibrations à base d'acrylate visco-élastique et une quantité efficace de silice hydrophobe. L'invention porte également sur des amortisseurs de vibrations mettant en ÷uvre un matériau d'amortissement à base d'acrylate visco-élastique ainsi que sur des articles renfermant de tels amortisseurs de vibrations.
