ABSTRACT:
Method of making attenuation sandwich panels having a cellular core positioned between and bonded to an imperforate facing sheet on one surface thereof and a perforate sheet with an outer layer of porous fabric material adhered to the other surface. The combined perforate facing sheet and porous fibrous material have a predetermined open surface area prior to its adherence to the cellular core. A coating of adhesive is applied to either the facing sheets or to the faying surface of the cellular core. The sheets are then properly positioned with respect to the cellular core. The porous fabric surface of the combined perforate sheet and porous fibrous material is positioned against a perforated plate. The opposite surface of the perforated plate is positioned against a bonding tool that has a plurality of longitudinal grooves on its perforated plate adjacent surface. This combination is then placed in a press or the like where pressure is applied from the facing sheets towards the core and is then heated until the adhesive is cured.
