To provide a honeycomb core capable of suppressing deformation of a honeycomb core caused by input of load in a direction vertical to a thickness direction of the honeycomb core when the honeycomb core is arranged along a curved surface of a part to be installed.SOLUTION: There is provided a honeycomb core in at least part of which a contour shape of each of a plurality of cells which are defined by cell walls is of a concave X-shape in a cross section orthogonal to a thickness direction. Each of a plurality of oblique wall parts which are provided on the cell walls is folded along 2n second ridge lines which are linear and extend in the thickness direction of the honeycomb core. In the concave X-shape of each cell, an interior angle at each apex from a second peak to the (n+1)th peak as counted from an end apex which is positioned at an end part of the concave X-shape in a ribbon direction is a reentrant angle, and an interior angle at each apex from the (n+2)th peak to the (2n+2)th peak is a convex angle, where X: 8n+2k (n is a natural number, and k is 2 or 3).SELECTED DRAWING: Figure 1
【課題】ハニカムコアを被設置部の曲面状の表面に沿わせて配置した際の、ハニカムコアの厚さ方向に対して垂直な方向に荷重が入力されることによる、ハニカムコアの変形を抑制する。【解決手段】少なくともその一部で、厚さ方向に直交する断面においてセル壁が画定する複数のセルの各々の輪郭形状が、凹Ｘ角形である。セル壁が備える複数の斜方壁部の各々は、ハニカムコアの厚さ方向に延びる直線状の２ｎ本の第２稜線に沿って折り曲げられる。複数のセルの各々の凹Ｘ角形において、リボン方向における当該凹Ｘ角形の端部に位置する端部頂点から起算して２番目からｎ＋１番目までの各頂点における内角は凹角であり、ｎ＋２番目から２ｎ+２番目までの各頂点における内角は凸角である。ただし、Ｘ：８ｎ＋２ｋ（ｎは自然数、ｋは２または３）【選択図】図１
