Abstract
An acoustic panel comprises a face sheet comprising a plurality of openings; a back sheet opposite to the face sheet; and an intermediate layer comprising a plurality of cells each comprising a cavity and a plurality of walls extending between the face sheet and the back sheet and surrounding the cavity. The plurality of walls can comprise at least one and possibly a plurality of slots for drainage. A method for making the acoustic panel is also described.
Claims20
An acoustic panel comprising:
- a face sheet comprising a plurality of openings;
- a back sheet opposite to the face sheet;
- and
- an intermediate layer comprising a plurality of cells, each of the plurality of cells defining a cavity and a plurality of walls extending between the face sheet and the back sheet and surrounding the cavity, at least one of the plurality of walls comprising at least one slot for drainage of liquid from the cavity.
A method for making an acoustic panel, the acoustic panel comprising a face sheet comprising a plurality of openings;
- a back sheet opposite to the face sheet;
- and an intermediate layer comprising a plurality of cells, each of the plurality of cells defining a cavity and a plurality of walls;
- the method comprising:
- joining the intermediate layer between the face sheet and the back sheet,
- defining at least one slot in at least one of the plurality of walls for drainage of liquid from the cavity;
- surrounding the face sheet and the back sheet over the cavity, so each of the at least one slot can drain liquid from the cavity.
An acoustic panel comprising:
- a face sheet comprising a plurality of openings;
- a back sheet opposite to the face sheet;
- and
- an intermediate layer comprising a plurality of cells, each of the plurality of cells defining a cavity and a plurality of walls extending between the face sheet and the back sheet and surrounding the cavity, at least one of the plurality of walls comprising at least one slot for drainage of liquid from the cavity, wherein each cavity is in fluid communication with at least one of the at least one slot for drainage of liquid from the cavity, wherein at least one slot in at least one of the plurality of walls comprises a plurality of slots for drainage of liquid from the cavity;
- and wherein the plurality of slots for drainage of liquid from the cavity comprises a plurality of slot sets and each of the slots in each of the plurality of slot sets in fluid communication with each other and aligned with a direction of drainage;
- and thus the slots for drainage of liquid from the cavity in each of the plurality of slot sets are aligned with the direction of drainage.
