Aircraft monuments with improved insulation and sound absorption

摘要

A protective shell for an aircraft galley wall is disclosed having an above work deck area and a below work deck area, the protective shell having an outer skin, an intermediate layer comprising vacuum insulated panels, and an interior layer comprising carbon fiber composite having a thickness that is greater than a thickness of the intermediate layer. In a preferred embodiment, the protective shell also includes an acoustic insulating layer made of an open cell acoustic foam that absorbs galley noise.
