Multilayer wall panel for military applications - has structure enclosed by profiled frame electrically coupled to central metal sheet

摘要

The wall panel (1) has 2 rigid foam sheets (4,5) lying on either side of a perforated metal sheet (6) and in turn enclosed between 2 outer protective layers (2,3) of fibre reinforced plastics. The layer structure is enclosed by a peripheral profile frame (7) which is lipped over the top and bottom edges of the wall panel. Pref. the profile frame (7) has a U-shaped cross-section with the base of the U contacting the peripheral edge of the layer structure, with the opposing arms respectively lipped over its top and bottom surfaces. A fixing flange (10) pref. projects outwards at one side of the profile frame (7). A pair of opposing tongues at the centre of the frame (7) are pref. used to form an electrical coupling with the perforated metal sheet (6). USE - For protection against splinters or projectiles and insulation against electromagnetic waves.
