Abstract
1. Многослойный элемент (1) для звукопоглощающей внутренней обшивки транспортного средства, преимущественно обшивки самолета, который содержит ! трехмерный сердечник (4, 15), который расположен между двумя покровными слоями (2, 3), которые идут главным образом параллельно с промежутком друг от друга, причем сердечник (4, 15) и оба покровных слоя (2, 3) имеют множество проходов (6) для передачи звука в виде перфораций, при этом сердечник (4, 15) имеет множество сквозных каналов (8, 16), расположенных рядом друг с другом и параллельно покровным слоям (2, 3), для дренажа жидкостей и вымывания посторонних объектов; ! при этом по меньшей мере один слой (5) звукопоглощения расположен по меньшей мере частично в области покровного слоя (2, 3). ! 2. Многослойный элемент (1) по п.1, в котором каналы (16) имеют боковые стороны (17), каждая из которых имеет непрерывную плоскую и/или изогнутую поверхность. ! 3. Многослойный элемент (1) по п.1 или 2, в котором каналы сердечника (8) имеют боковые стороны (9), которые образованы за счет множества главным образом плоских и/или изогнутых поверхностей (10), которые примыкают друг к другу под углом (14) меньше, чем 180°. ! 4. Многослойный элемент (1) по п.1, в котором сердечник (4, 15) имеет повторяющуюся треугольную, трапецеидальную, прямоугольную или волнистую геометрию поперечного сечения. ! 5. Многослойный элемент (1) по п.1, в котором проходы (6) выполнены в виде цилиндрических, эллиптических или многоугольных отверстий. ! 6. Многослойный элемент (1) по п.1, в котором слой (5) звукопоглощения выполнен как теплоизоляционный слой. ! 7. Многослойный элемент (1) по п.1, в котором сердечник (4, 15) и/или покровные слои (2, 3) выполнены из пластмассы. ! 8. � 1. The multilayer element (1) for sound-absorbing inner lining of the vehicle, mainly the lining of the aircraft, which contains! a three-dimensional core (4, 15), which is located between two cover layers (2, 3), which go mainly parallel to the gap from each other, and the core (4, 15) and both cover layers (2, 3) have many passes (6) for transmitting sound in the form of perforations, while the core (4, 15) has many through channels (8, 16) located next to each other and parallel to the coating layers (2, 3), for draining liquids and washing foreign objects ; ! wherein at least one sound absorption layer (5) is located at least partially in the region of the coating layer (2, 3). ! 2. The multilayer element (1) according to claim 1, in which the channels (16) have lateral sides (17), each of which has a continuous flat and / or curved surface. ! 3. The multilayer element (1) according to claim 1 or 2, in which the channels of the core (8) have lateral sides (9), which are formed due to the set of mainly flat and / or curved surfaces (10) that are adjacent to each other at an angle (14) less than 180 °. ! 4. The multilayer element (1) according to claim 1, in which the core (4, 15) has a repeating triangular, trapezoidal, rectangular or wavy geometry of the cross section. ! 5. The multilayer element (1) according to claim 1, in which the passages (6) are made in the form of cylindrical, elliptical or polygonal holes. ! 6. The multilayer element (1) according to claim 1, in which the layer (5) of sound absorption is made as a heat-insulating layer. ! 7. The multilayer element (1) according to claim 1, in which the core (4, 15) and / or cover layers (2, 3) are made of plastic. ! 8. �
