Abstract

A panel assembly that includes a first panel having an inner surface and an outer surface, and a second panel having an inner surface and an outer surface. The second panel includes a plurality of rib members formed therein that extend inwardly. The rib members include an inner surface and an outer surface. A plurality of panel portions are defined between the plurality of rib members. The panel portions include an inner surface and an outer surface. The inner surface of the rib members are secured to the inner surface of the first panel, and the inner surface of the panel portions is spaced apart from the inner surface of the first panel to define at least first and second cavities.

Claims

1. A panel assembly comprising:

a first panel having an inner surface and an outer surface, and

a second panel having an inner surface and an outer surface, wherein the second panel includes at least first and second rib members formed therein that extend inwardly, wherein the first and second rib members each include an inner surface and an outer surface, wherein at least a first panel portion is defined between the first and second rib members, wherein the first panel portion includes an inner surface and an outer surface, wherein the inner surfaces of the first and second rib members are secured to the inner surface of the first panel, and wherein the inner surface of the first panel portion is spaced apart from the inner surface of the first panel to define at least a first cavity and the inner surface of the second panel portion is spaced apart from the inner surface of the second panel to define at least a second cavity.

2. The panel assembly of claim 1 further comprising a first acoustic treatment member positioned in the first cavity.

3. The panel assembly of claim 2 wherein the first acoustic treatment member is adhered to at least one of the inner surface of the first panel or the inner surface of the second panel.

4. The panel assembly of claim 3 wherein a space is defined between the first acoustic treatment member and one of the inner surface of the first panel or the inner surface of the second panel.

5. The panel assembly of claim 4 wherein the first acoustic treatment member is comprised of at least first and second layers.

6. The panel assembly of claim 3 wherein the first acoustic treatment member is adhered to the inner surface of the second panel, and wherein the first and second panel portions each include a plurality of raised portions defined therein.

7. The panel assembly of claim 3 further comprising a second acoustic treatment member, wherein the first acoustic treatment member is adhered to the inner surface of the first panel and the second acoustic treatment member is adhered to the inner surface of the second panel, and wherein a space is defined between the first and second acoustic treatment members.

8. The panel assembly of claim 2 wherein the second cavity defines a ducting space.

9. The panel assembly of claim 8 wherein the second cavity does not include an acoustic treatment member therein.

10. The panel assembly of claim 5 further comprising an outer acoustic treatment member adhered to at least a portion of the outer surface of at least the first and second panel members, and wherein an outer rib cavity is defined between the outer acoustic treatment member and the outer surface of the rib member.

11. The panel assembly of claim 10 further comprising a decorative panel adhered to the outer surface of the first panel member.

12. A panel assembly comprising:

a first panel having an inner surface and an outer surface, and

a second panel having an inner surface and an outer surface, wherein the second panel includes a plurality of rib members formed therein that extend inwardly, wherein the rib members include first and second side walls, an inner surface and an outer surface, wherein a plurality of panel portions are defined between the plurality of rib members, wherein the panel portions include an inner surface and an outer surface, wherein the inner surface of the rib members are secured to the inner surface of the first panel, wherein the inner surface of the panel portions is spaced apart from the inner surface of the first panel to define at least first and second cavities, and wherein the first and second side walls of the rib members do not include any openings defined therein.
