Abstract
First and second sandwich panels each have first and second face sheets, held in a mutually parallel, spaced-apart relationship by a low-density core. The panels are joined along an edge, which may be curved. The joinder is made by a plurality of thin, flat "L"-shaped joining pieces, each having first and second legs, which may be at skew angles if the panels are joined at skew angles. The first leg of the first joining piece is affixed, as by adhesive, to the first face sheet of the first panel and to the exposed core of the second panel, and the second leg of the first joining piece is affixed to the second face sheet of the second panel. The second joining piece, adjacent the first, has its first leg affixed to the first face sheet of the second panel and to the exposed core of the first panel, and its second leg affixed to the second face sheet of the first panel. Other additional fasteners may alternate along the length of the edge to be joined. In a particular embodiment, the first legs of the joining pieces are coupled in common.
