no. 1 example

[0055] According to the first embodiment of the present invention, in the honeycomb structure, one or both ends of the honeycomb material in the vertical direction are provided with protruding portions protruding from the surface of the filling material by a predetermined length.

[0056] When using the honeycomb structure with the above-mentioned protruding part as the core material and bonding the surface material on it to manufacture a sandwich panel, the adhesive is only applied to the front end of the protruding part, and the adhesive is not applied to the surface of the filling material. Sandwich panel manufacturing methods are available.

no. 2 example

[0058] In the second embodiment of the present invention, in the above-mentioned honeycomb structure, two filling sheets are filled in the longitudinal direction of the honeycomb material honeycomb, and between the two layers of filling material layers inside the honeycomb material, there is no filling material. air layer.

[0059] Since the air layer of this embodiment is provided in the honeycomb structure, the sound-absorbing performance from low frequency to high frequency is improved, so that a sound-absorbing material corresponding to full audio frequency can be obtained.

no. 3 example

[0061] In the third embodiment of the present invention, in the above-mentioned honeycomb structure, the two honeycomb materials are pressed into the two honeycomb materials from the upper and lower sides of the sheet-like phenolic foam material whose thickness exceeds the total height of the two honeycomb materials. There is no honeycomb material in the middle part, and a layer consisting of filling material only is provided.

[0062] By providing an intermediate layer (there is no layer of honeycomb material) consisting only of the filling material of this embodiment in the honeycomb structure, the heat conducted to the wall of the honeycomb material is blocked by the intermediate layer, and the foam material constituting the intermediate layer becomes an insulating material. thermal layer. If the middle layer is thickened, the thermal insulation performance is improved, and the honeycomb material layer on both sides becomes the protective layer of the foam material.

Abstract

The height and width of a sheet-like filler material before it is placed in a cell of a honeycomb material is set greater than those of the honeycomb material, and after the placement, peripheral edges of the honeycomb material are fringed with filler materials to prevent a filler material from falling out of an end section cell. A liquid adhesive agent is applied to the top of cell walls facing one surface of the honeycomb material, and a surface material is pressed to that surface of the honeycomb material to which the adhesive agent is applied. Then, before the adhesive agent hardens, water-absorbing foam materials are placed in cell spaces by pressing them into the cell spaces rom the other surface of the honeycomb material until they are in contact with the adhesive agent. The foam material is quickly adhered to the honeycomb material.

Description

technical field [0001] The invention relates to a gas-permeable sandwich panel and a manufacturing method thereof, which uses a honeycomb structure filled with a phenolic foam material with a connected cell structure as a core material, and uses a gas-permeable porous material as a surface material. Background technique [0002] The structure with honeycomb material as the core material is mostly used for wall and ground materials of aircraft, railway vehicles, and building materials. As the purpose of use of the honeycomb structure, in addition to the use as a sound insulating material, it is also an important use as a sound absorbing material. [0003] In this specification, a sound-insulating material is a honeycomb that has been filled or not filled with a honeycomb material, and a non-breathable surface material is pasted on both sides to block the sound transmission; The honeycomb is filled with a porous body, and a gas-permeable surface material is attached to at lea...
