Abstract

1373063 Honeycomb-cored sandwich laminates AVIONS MARCEL DASSAULT-BREGUET AVIATION 8 March 1972 [9 March 1971] 10880/72 Heading B5N [Also in Division F2] A sound-absorbent panel comprises a honeycomb structure 2 sandwiched between two surfaces 1, 5, at least one of which is porous, the walls 3 of the honeycomb cells being provided with openings 4 adjacent at least one of the surfaces of the panel. The surfaces 1, 5 and the structure 2 are of metal or porous plastics materials and are assembled to form a rigid panel by means of a suitable adhesive resin. A particular application is the lining of the air intake or exhaust of a jet engine, in which case as shown in Fig. 2, the openings 4 have their bases against a perforated skin 1 and an impervious sheet 5. This configuration combines acoustic advantages with facilities to drain stray, unwanted liquids, and also facilitates shaping in the case of curved panels. Although only a single sandwich is shown, it is possible to superimpose two or more layers. Other applications include the sound insulation of ventilation shafts and hot-air heating shafts, airport muffling devices, sound-deadening on industrial or public sites, and improving the acoustics of large rooms.
