Patent Images
1. A laminated panel comprising at least:
- (a) a first metal layer having a thickness of less than about 1 mm and comprising a first section, a second section generally coplanar with the first section and a first splice line between the first and second sections;
(b) a second metal layer having a thickness of less than about 1 mm and comprising a first section, a second section generally coplanar with the first section and a second splice line between the first and second sections, the second splice line being spaced laterally from the first splice line by at least several centimeters; and
(c) a fiber reinforced adhesive layer between the first and second metal layers.

Abstract
A laminated body panel for aircraft applications comprises first and second metal layers and an adhesive layer. First and second sections in each metal layer are generally coplanar and separated by a splice line. A first splice line in a first metal layer is generally parallel to a second splice line in a second metal layer, and spaced laterally from the second splice line. An adhesive layer between the metal layers preferably contains reinforcing fibers bridging across the splice lines. An aircraft fuselage or wing or empennage made with spliced body panels of the invention has fewer joints and weighs less than one made with narrower body panels containing unspliced metal layers.

27. A laminated panel comprising at least:
-
(a) a first aluminum alloy layer having a thickness of less than about 1 mm and comprising a first section, a second section generally coplanar with the first section and a first splice line between the first and second sections; (b) a second aluminum alloy layer having a thickness of less than about 1 mm and comprising a first section, a second section generally coplanar with the first section and a second splice line between the first and second sections, the second splice line being generally parallel to the first splice line and spaced laterally therefrom by at least several centimeters; and (c) an adhesive layer between the first and second aluminum alloy layers, said adhesive layer comprising a synthetic polymer reinforced with fibers comprising a material selected from the group consisting of glass, E-glass, R-glass, S2-glass, aramids, poly-paraphenyleneterephthalamide and carbon. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37)
