ABSTRACT:
A member for a honeycomb core or panel that can be bent with various radii of curvature, can contour a compound curvature and can support a load perpendicular to the defined curvature. The honeycomb member, preferably, has cells having an equilateral triangular cross section. The cells are defined by rectangular bottom, top and side faces. The connecting angle between each bottom face and each side face is typically about 60 degrees. The adjoining sides of the bottom faces contact each other. The adjoining sides of the top faces also contact each other. Although the cells contain a small orifice between adjoining sides, the cells have the same strength as that of completely enclosed cells. Furthermore, the relative position of the adjoining cells can be easily altered.
