Appl. No.:

15/495314

Inventors:

- Bethesda MD, US
Vernecia Sharaé Meredith - Marietta GA, US
Charles J. Novak - Marietta GA, US

International Classification:

B64C 1/40
B32B 5/18
B32B 5/32
B64D 7/00

Abstract:

A method includes determining a target acoustic profile based on acoustic conditions at an exterior surface exposed to weather. The method further includes determining a plurality of foam layer characteristics based on the target acoustic profile. The method further includes determining one or more of elastomer characteristics based on the target acoustic profile and the plurality of foam layer characteristics. The method further includes providing a foam layer comprising the plurality of foam layer characteristics. The method further includes depositing an elastomer into the provided foam layer according to the one or more elastomer characteristics. The method further includes coupling the foam layer comprising the deposited elastomer onto the exterior surface exposed to weather. The foam layer including the deposited elastomer absorbs acoustic energy corresponding to the target acoustic profile.

Abstract:

An apparatus includes a foam layer, a coating layer and an elastomer. The foam layer includes a first surface for coupling the apparatus to a surface exposed to weather, a second surface opposite the first surface, and a plurality of pores within the foam layer. The coating layer is deposited on the second surface of the foam layer. The elastomer is deposited within the plurality of pores within the foam layer.
