CORE MATERIAL FOR SANDWICH PANEL, CORE FOR SANDWICH PANEL, AND SANDWICH PANEL
PROBLEM TO BE SOLVED: To provide core materials for a sandwich panel having high flexural rigidity, strong adhesion to a skin material and capable of obtaining a sufficient die-cutting gradient.SOLUTION: Core materials 1, 100 for a sandwich panel have: a first flat surface 5 formed at the side of a first face 3; plural protrusions which have second flat surfaces 41 parallel to the first flat surface 5 at the top faces, have the prescribed intervals around the first flat surface 5 and protrude from the second surfaces 41 toward the first surface 5; and the recesses 7 being spaces formed by the first flat surface 5 and plural sidewall faces 42, 43 of plural protrusions 4 disposed around the first surface 5. The protrusion 4 and the recess 7 of the core materials 1, 100 are formed into the shapes of the recess 7 and the protrusion 4 in which the split parts obtained by splitting the polyhedron having a space packing shape at an equatorial part are mutually fitted in. The protrusion 4 has the plural first sidewall faces 42 having a first polygonal flat surface, and the plural second sidewall faces 43 having a second polygonal flat surface.SELECTED DRAWING: Figure 2
【課題】曲げ剛性が大きく、スキン材との接着力が強く、また十分な型抜き勾配が得られるサンドイッチパネル用コア材を提供する。【解決手段】第１面３側に形成される平坦な第１平坦面５と、第１平坦面５と平行で平坦な第２平坦面４１を頂面に有し、第１平坦面５の周囲に所定の間隔を有して、第２面側４１から第１面５側に向けて突出する複数の凸部と、を有し、第１平坦面５及び第１平坦面５の周囲に配置される複数の凸部４の側壁面４２、４３で形成される空間を凹部７とするサンドイッチパネル用コア材１，１００であって、凸部４と凹部７とは、空間充填形状をなす多面体を赤道部分で２分割した分割部分が互いに嵌合し合う凹部７と凸部４の形状に形成され、凸部４の側壁面は、第１の多角形平面の複数の第１側壁面４２と、第２の多角形平面の複数の第２側壁面４３とを有するサンドイッチパネル用コア材１，１００。【選択図】図２
