To provide a honeycomb core capable of enhancing the strength of a curved surface honeycomb panel.SOLUTION: There is provided a honeycomb core in which, at least partially, a contour shape of each of a plurality of cells which is defined by cell walls on a side surface on one side of a thickness direction is a hexagon, and a contour shape of each of a plurality of cells defined by the cell walls on a side surface on the other side of the thickness direction is an X-shape. The cell wall is folded along a linear ridge line which extends from an apex of the hexagon toward a peak of the X-shape. Y ridge lines extend from each peak of the hexagon, where X: 8n+2k and Y: 2n+1 (n is a natural number and k is an integer of 0 or greater and 3 or smaller) are satisfied.SELECTED DRAWING: Figure 1
【課題】曲面ハニカムパネルの強度を向上させることが可能なハニカムコアを提供する。【解決手段】少なくとも一部で、厚さ方向一側の側面上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六角形であり、厚さ方向他側の側面上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Ｘ角形である、ハニカムコア。セル壁は、前記六角形の頂点から前記Ｘ角形の頂点にかけて延びる直線状の稜線に沿って折り曲げられている。稜線は、前記六角形の各頂点からＹ本ずつ延びている。ただし、Ｘ：８ｎ＋２ｋ、Ｙ：２ｎ＋１（ｎは自然数、ｋは０以上３以下の整数）【選択図】図１
