Abstract: Fluoropolymer structures are provided for use in aircraft interiors. The structures include an external cross-linked fluoropolymer layer that is lighter and safer than conventional fluoropolymer film layers. In general these structures can be described as a panel for the interior of an aerospace vehicle made of an aluminum or fiber composite facesheet, a foam or honeycomb core attached to the facesheet, and a layer of cross-linked fluoropolymer on the surface of the facesheet that is on the side facing away from the core. Methods of making and using the structures are also provided.
