AIRCRAFT INTERIOR PANEL WITH ACOUSTIC MATERIALS

摘要

A panel assembly (10) comprises a first panel (12) having an inner surface (12a) and an outer surface (12b), and a second panel (14) having an inner surface (14a) and an outer surface (14b). The second panel (14) includes at least first and second rib members (16) formed therein that extend inwardly. The first and second rib members (16) each include an inner surface (16a) and an outer surface (16b). At least a first panel portion (18) is defined between the first and second rib members (16). The first panel portion (18) includes an inner surface (18a) and an outer surface (18b). The inner surface (16a) of the first and second rib members (16) are secured to the inner surface (12a) of the first panel (12). The inner surface (18a) of the first panel portion (18) is spaced apart from the inner surface (12a) of the first panel (12) to define at least a first cavity (22), and the inner surface (18a) of the second panel portion (18) is spaced apart from the inner surface of the second panel to define at least a second cavity.
