Sandwich element for the sound-absorbing inner cladding of means of transport, especially for the sound-absorbing inner cladding of aircraft

摘要: The invention relates to a sandwich element (1) for the sound-absorbing inner cladding of means transport, especially aircraft, comprising three-dimensionally constructed core structure (4, 15) which is disposed between two cover layers (2, 3) run substantially parallel one another at distance. According invention, plurality passages (6) sound transmission are incorporated in and/or least 3), wherein absorption layer (5) area parts. As result presence and (4,15), elements according has good properties heat insulating properties. allows through (1). formed by channels (8, 16) arranged adjacent preferably inclined installation (1), foreign bodies have penetrated into example as introduction cleaning liquid or condensation can be flushed out again. Depending on application, possibly sufficient effect achieved even without (5). ventilation additionally prevents long-term could corrosion rotting processes.
