面状のハニカムコアを成形することができなかった。Detailed Description of the Invention "Industrial Application Field" The present invention relates to a honeycomb core in more detail, and particularly relates to a honeycomb core suitable for various curved surface moldings. ” Honeycomb cores are characterized by being easy to form and having the highest weight-specific strength, and are generally formed by stretching and are made up of planar aggregates of hollow columnar cells in an approximately regular hexagonal shape. has been done. However, when forming a curved honeycomb core using such a honeycomb core,
For example, when the honeycomb core is curved in the stretching direction (or ribbon direction) along the curved surface shape, the direction perpendicular to the stretching direction (or ribbon direction) of the honeycomb core, that is, the ribbon direction (or stretching direction) is upwardly curved. If the cell shape is warped, the saddle shape is distorted, or it does not fit the curved surface shape, and you try to fit it by applying excessive force, the cell shape may break or the bonded part may peel, so It was not possible to mold a high-quality curved honeycomb core.

The spacing between the cell walls 22.22 does not change on either side of the concave curved surface or convex curved surface 1, and the spacing in the ribbon direction contracts on the concave curved surface side and expands on the convex curved surface side; The expansion and contraction of the spacing causes twisting deformation of each cell wall 23, 23... located perpendicular to the ribbon direction, and most of the resulting deformation is absorbed by the elastic deformation of the material.
The cell walls 22, 22..., 23, 23... have the property of easily fitting into a curved shape without causing breakage or peeling of the adhesive portion, and without causing the phenomenon that the expansion direction W is warped. have

。However, on the other hand, when curved in the stretching direction W, the cell walls 23, 23... are located in a straight line in the stretching direction W, and this state exists in the shape of a single plate. , since the bending rigidity is large to make it curve in this direction,
It has been extremely difficult to form a honeycomb core with a curved surface that is curved in the stretching direction W. Therefore, such a honeycomb core 20 has a drawback that it is not suitable for molding a honeycomb core having a complex curved surface such as a high-quality cubic surface.

In the core, each of the cells has a planar shape, and the end faces of the cells adjacent to each other in the direction of expansion are in contact with each other, and the cells are arranged in a straight line along the direction of expansion. The direction perpendicular to the expansion direction (
The cells arranged in a straight line adjacent to each other in the ribbon direction are arranged so as to be alternately shifted by half a pitch in the stretching direction.
「作用」 本発明は上記手段よりなるので、以下の如く作用する。"action" Since the present invention comprises the above means, it operates as follows.

成されている。In other words, each cell having a substantially drum shape is arranged in a positional relationship in which the end surfaces of the adjacent cells are in contact with each other in the stretching direction, and are aligned in a straight line along the stretching direction. The cell walls located along the line are formed in a zigzag shape.

とができる。Therefore, when curved in the extension direction along the curved shape,
The spacing between the cell walls in the stretching direction of each cell contracts on the concave curved surface side and expands on the convex curved surface side, but this expansion and contraction of the spacing between the cell walls in the stretching direction is caused by the cell walls located in a zigzag pattern along the stretching direction. However, in particular, in the central constriction of the roughly drum-shaped cells, torsional deformation occurs such that the interval contracts on the concave curved side and expands on the convex curved side, and the resulting torsional deformation is mostly due to the deformation of the material. Since it is absorbed, it can easily fit into a curved shape without causing breakage of the cell wall or peeling of the adhesive part. Therefore, it is possible to form a curved honeycomb core with a high quality and a large curvature in the stretching direction, so it is possible to easily form a honeycomb core with a complicated curved surface such as a cubic curved surface.
