Abstract

A multilayer structural element, such as a skin panel for an aircraft fuselage, comprises a plurality of metal webs and a plurality of fiber webs arranged as layers in a sandwich structure, where the metal webs of neighbouring layers form stepped connecting regions. A material strip is provided on an outer surface of the sandwich structure for at least partially covering an outlying connecting region, and the material strip enables the placement of rivets at uniform spacing for fastening a structure to the structural element.
