Abstract
Vibration-damping layers are stored as a continuous elongated strap in cod condition for supply to subsequently fabricated structural products. Such strap is formed from high modulus layer constrainment segments encapsulated within a viscoelastic material contributing to establishment of the vibration-damping property and flexure of the strap between the segments thereof to accommodate coiling during storage. The strap is uncoiled from its storage condition during a supply phase to a preselected surface of the fabricated structural product.
Claims9
In combination with a method for fabrication of a structural product including formation of a surface thereon and application of a vibration-damping layer to said surface, the improvement residing in the steps of:
- forming said vibration-damping layer as an elongated strap having constrainment segments therein encapsulated within a flexible coating prior to said formation of the surface on the structural product during fabrication thereof;
- storing the elongated strap in a coiled condition accommodated by flexure of said flexible coating;
- and supplying the structural product during said fabrication thereof with the elongated strap for application to said surface by uncoiling of the strap from storage in said coiled condition.
In combination with a method for fabrication of a structural product including formation of a surface having a vibration-damping layer thereon, the improvement residing in the steps of:
- forming said vibration-damping layer as an elongated strap having an outer flexible coating prior to formation of the surface during said fabrication of the structural product;
- storing the elongated strap in a coiled condition accommodated by flexure of the flexible coating;
- and uncoiling the elongated strap stored in said coiled condition for continuous supply during application to said surface of the structural product being fabricated.
