COMPOSITE LAMINATE HAVING A DAMPING INTERLAYER AND METHOD OF MAKING THE SAME

Composite laminates used in structural applications include an interlayer of soft material that provides damping action to reduce noise and vibration. The interlayer may comprise a viscoelastic material which deforms under stress caused by shock, noise or vibration. A reinforcement may be embedded i...

Beschreibung
Zusammenfassung:	Composite laminates used in structural applications include an interlayer of soft material that provides damping action to reduce noise and vibration. The interlayer may comprise a viscoelastic material which deforms under stress caused by shock, noise or vibration. A reinforcement may be embedded in the viscoelastic material to maintain the mechanical strength and stiffness of the laminate. The reinforcement may include individual or woven fibers or ridged tubes that provide the interlayer with stiffness. L'invention concerne des stratifiés composites utilisés dans des applications structurelles et comprenant une couche intermédiaire de matériau mou qui fournit une action d'amortissement pour réduire le bruit et les vibrations. La couche intermédiaire peut comprendre un matériau viscoélastique qui se déforme sous la contrainte provoquée par un choc, un bruit ou des vibrations. Un renforcement peut être enrobé dans le matériau viscoélastique pour maintenir la résistance et la rigidité mécanique du stratifié. Le renforcement peut comprendre des fibres individuelles ou tissées ou encore des tubes munis de nervures qui donnent de la rigidité à la couche intermédiaire.
