Definitions
- a second object of the present invention is to provide a structure and a manufacturing method in which even when the thickness of the sound absorbing foam material is increased in order to improve the sound absorbing performance, the honeycomb material can be well filled. Furthermore, when attaching the face material to the honeycomb material in manufacturing the core material on both sides, it is important to minimize the influence of the adhesive hardening time, thereby shortening the manufacturing time and improving the productivity. This is the third issue. Furthermore, to reduce the thickness of the panel by avoiding the thickness of the panel from becoming larger than the thickness required from the acoustic characteristics due to the provision of the projection of the honeycomb material for attaching the face material. is the fourth problem.
- the height of the cell walls of the honeycomb material that is, the thickness of the honeycomb material is naturally less than half the thickness of the foam material. It is possible to avoid the problem that the honeycomb material is deformed and cannot be pushed in when filling, and at the same time, the second problem can be solved.
- FIG. 1(b) two straight lines connecting the upper and lower ends of the walls forming the cell are drawn. This straight line indicates that the edge of the cell wall beyond plane A is visible rather than a cross-section. This straight line is omitted in the following explanatory diagrams.
- the honeycomb material is already filled with the foam material, and the tip of the honeycomb material protrudes from the foam material by more than 2 mm, for example, the same operation is performed. It is expected that the adhesive will not be touched. However, in practice, the honeycomb material and the foam material themselves bend due to the weight of the foam material, so that the surface of the foam material is often wetted with the adhesive. A projection length of, for example, 10 mm or more may be necessary to ensure that the surface of the foam material is not wetted by the adhesive.
- FIG. 5 is a cross-sectional view showing the concept of a state in which an adhesive is attached to the tip of one wall surface of the honeycomb material. It can be seen that the adhesive material 15 adheres to the tip of the wall surface 111 of the honeycomb material in the form of water droplets.
- the cross section of the tip portion of the wall surface 111 forming the cells of the honeycomb material 11 strongly pressed against the air-permeable material 13 is deformed into an inverted T shape.
- a part of the adhesive 15 adhering to the tip portion of the wall surface 111 flows to the bottom of the inverted T shape and permeates the air-permeable material 13 .
- the adhesive 15 flows along the surface of the air-permeable material 13 toward the wall surface of the adjacent cell, clogs the cell openings and impairs the sound absorption performance. is attached only to the tip of the wall surface 111 .
- the core material is completed when the adhesive 15 that bonds the air-permeable material 13 and the honeycomb material 11 is completely solidified. Therefore, it can be said that the core material preparation time is governed by the time A (natural drying and complete solidification time) related to the adhesive.
- the acoustic double-sided honeycomb panel can maintain a predetermined air permeability without spreading the adhesive attached to the tip of the honeycomb material to the surface of the air-permeable material 13a, the air-permeable material 13b, or the foam material 12, which is the first problem. structure was realized.

Abstract
Le premier problème décrit par la présente invention est d'utiliser une structure et un procédé de fabrication dans lesquels un matériau d'une face ayant une perméabilité à l'air souhaitée peut être disposé sur n'importe quelle face d'un panneau en nid d'abeilles acoustique à double face. Le deuxième problème est d'utiliser une structure dans laquelle un matériau en nid d'abeilles est rempli de manière satisfaisante, même si l'épaisseur d'une mousse absorbante est augmentée. Le troisième problème est de raccourcir les délais de fabrication et d'améliorer la productivité. Le quatrième problème est de réduire l'épaisseur du panneau. La solution selon l'invention porte sur un panneau souhaité qui peut être obtenu au moyen d'une structure dans laquelle un matériau de face est relié à deux matériaux en nid d'abeilles ayant une épaisseur totale inférieure à l'épaisseur d'une mousse absorbante pour former deux matériaux centraux, les deux matériaux centraux étant pressés à partir des deux faces de la mousse absorbante. En outre, dans cette structure, l'épaisseur du matériau en nid d'abeilles peut être inférieure ou égale à la moitié de l'épaisseur de la mousse absorbante, grâce à quoi, lorsqu'il est rempli de mousse absorbante, le matériau en nid d'abeilles est moins susceptible de se déformer et peut être rempli de manière satisfaisante. La productivité est améliorée en superposant les temps de solidification de l'adhésif. L'épaisseur est réduite, ce qui empêche une extrémité du matériau en nid d'abeilles de faire saillie de la mousse.
