SANDWICH ELEMENT FOR SOUND-ABSORBING INNER CLADDING OF TRANSPORT MEANS, ESPECIALLY FOR SOUND-ABSORBING INNER CLADDING OF AIRCRAFT FUSELAGE CELLS

摘要

A sandwich element for a sound-absorbing inner cladding of transport means, such as aircraft fuselage cells, comprising a honeycomb-shaped core structure and cover layers applied to both sides of the core structure. At least one cover layer is constructed as permeable to air at least in sections and a covering is disposed at least in sections on at least one cover layer, wherein a sound absorption layer is disposed at least in sections in the area of at least one cover layer. A plurality of passages in the cover layers allow efficient transmission of the sound impinging on the sandwich element from outside as far as the sound absorption layer of the sandwich element.
