ことができるものである。(Prior technology) Conventionally, so-called honeycomb panel structures with a sandwich structure, in which a honeycomb core material with many honeycomb-shaped spaces formed inside is integrated with face plates on both sides, are lightweight and resistant to bending and compressive stress. Due to its strength, vehicle body materials,
It is widely used in various industrial fields as an aircraft body material or building material. And in general,
As shown in FIG. 5, the honeycomb core material a used in this honeycomb panel structure has a plurality of strip-shaped core sheets b, b, . C, C, . . . are formed into sections, and the above characteristics can be provided by the honeycomb-shaped spaces C, C, .
ところで、上述の如きハニカムパネル構造体を各種の産

。By the way, when the honeycomb panel structure as described above is applied as various industrial materials, it is not always used in a flat state, and it may often be necessary to form a curved surface. However, when bending stress acts on the honeycomb core material a of the honeycomb panel structure, tensile stress acts on the convex curved surface side of the core material a, and compressive stress acts on the concave curved surface side of the core material a. There was a problem in that the core material a was deformed into a saddle-shaped curve as shown in FIG. 4, making it impossible to form a desired curved surface.
このようにハニカムコア材ａが曲面形成時に鞍形変形す
るのは、各ハニカム状空間Ｃを区画形成する６つの仕切
壁ｄ−ｉのうち図で矢印で示す展張方向と直交する仕切
壁ｅ、ｈ以外の仕切壁ｄ。In this way, the honeycomb core material a undergoes saddle-shaped deformation when forming a curved surface because, among the six partition walls d-i that partition and form each honeycomb-shaped space C, the partition wall e, which is orthogonal to the expansion direction indicated by the arrow in the figure, Partition wall d other than h.
ｆ、ｇ、ｉが原因であり、しかもその展張方向と直交す

大きい場合はど鞍形変形が起こり易いという事実がある
。f, g, and i are the causes, and it is a fact that saddle-shaped deformation is likely to occur if the opening angle θ made with respect to the line X perpendicular to the expansion direction is large, that is, if the expansion rate is large.

Surin 1 ~ on the side of honeycomb core material a where compressive stress acts
The compressive stress that occurs when forming a curved surface is absorbed and relaxed by the engagement of the notched ends of each of the slits, thereby eliminating saddle-shaped deformation and forming a desired curved surface. What has been done is known.
（発明が解決しようとする問題点）
ところが、上記の従来のものは曲面形成を可能にするた

に手間がかかつて煩わしいという問題があった。(Problems to be Solved by the Invention) However, the above-mentioned conventional product has slits to enable the formation of curved surfaces, making it weak in strength, and moreover, it is difficult to manufacture as it requires 110 slits. In the past, there was a problem that it was time-consuming and troublesome.

にある。The present invention has been made in view of this point, and its purpose is to focus on the cause of the saddle-shaped deformation as described above, and to provide the above-mentioned partition wall d in the bent portion of the core material a,
By partially varying the expansion rate of the core material a so that the opening angle θ formed with respect to the line
The compressive stress acting on i is made as small as possible, thereby creating a honeycomb panel structure that is bent into a desired curved shape without saddle-shaped deformation while maintaining the strength of the bent portion without forming any slits. The aim is to make it easy for you to get used to it.

れたハニカムパネル構造体を得る方法にする。(Means for Solving the Problems) In order to achieve the above object, the solving means of the present invention firstly consists of a large number of core sheets coated with adhesive at predetermined intervals, each having 15 coats of adhesive. An M carcass is prepared by laminating and bonding the carcasses so that they are positioned with a certain regularity. Then, this laminate is expanded so that the expansion rate of the portion that will become the bent portion is small to form a honeycomb core material having honeycomb-shaped spaces between the core sheets. Next, after the core material is bent, face plates are bonded to both sides of the core material to obtain a honeycomb panel structure bent into a curved shape.

A honeycomb panel structure is thereby obtained.

スリットを設けずに折り曲げることができるので折曲部
の強度が確保されることとなる。In this case, since the above-mentioned laminate is set so that the expansion rate of the portion that becomes the bending part of the honeycomb core material formed by stretching is small, the core material after stretching becomes the bending part. The core density of the part is higher than that of other parts, and this makes the expansion direction of the partition walls other than the partition walls that are orthogonal to the expansion direction of the partition walls that partition and form the honeycomb-shaped space of the part that becomes the bending part The aperture color image made with orthogonal lines becomes smaller. Therefore, when the honeycomb core material is bent, the opening angle of the partition wall becomes larger on the convex curved surface side of the bent part due to the effect of the strain stress, but on the concave curved surface side, the opening angle is set smaller as described above. By doing so, the effect of compressive stress is made as small as possible, so saddle-shaped deformation does not occur, and therefore a honeycomb panel structure with a desired curved surface shape can be obtained. Also,
Since it can be bent without providing a slit, the strength of the bent portion is ensured.

At this time, since the wall thicknesses, that is, the rigidities of the core sheets 3, 3- of the laminate 2 are partially different, this difference in rigidity causes the low-rigidity core sheets 3, 3, 3- of the laminate 2 to differ.

Since the opening angle θ is naturally set to be smaller than that of the partition wall, the opening angle θ of the partition wall becomes larger due to the action of tensile stress on the convex curved surface side of the bent part formed by bending. However, on the concave curved surface side, the effect of compressive stress is as small as possible, so saddle-shaped deformation does not occur.
