Claim:
1. A method of manufacturing a core stiffened structure, the core stiffened structure having a first face sheet, a second face sheet, and a plurality of wafers of composite core, the method comprising: orienting the plurality of wafers in a non-uniform pattern onto the first face sheet, the non-uniform pattern producing non-uniform spacing between adjacent wafers, each wafer having a plurality of hexagonal cell members, each hexagonal cell member having a cell wall that terminates at a first surface network and a second surface network, the plurality of hexagonal cell members assembled together such that a perimetrical shape of the wafer is hexagonal with the plurality of hexagonal cell members being oriented with adiacent cell walls in a pattern that results in the perimetrical shape of the wafer being hexagonal in that outerwardly exposed cell walls of the plurality of cell members create the perimetrical shape; assembling a second face sheet onto the plurality of wafers; and curing an adhesive to create a bond between the plurality of wafers, the first face sheet, and the second face sheet.
