Abstract:
1. A method of producing a composite panel having an upper side and a lower side, comprising the steps of: arranging a plurality of preformed elongated strips of low density cellular material to form a core panel, wherein the elongated strips have a generally rectangular cross-section having flat and opposite side surfaces and with adjacent elongated strips having flat and opposing edge surfaces extending between the side surfaces, wherein the side surfaces are generally perpendicular to the edge surfaces within each strip; adhesively attaching a first sheet of flexible material to the side surfaces of each of the elongated strips facing the upper side of the composite panel; adhesively attaching a second sheet of flexible material to the side surfaces of each of the elongated strips facing the lower side of the composite panel; and, extending portions of the second sheet between the opposing edge surfaces of adjacent elongated strips, and limiting flexing of the panel with the second sheet.
