Monolithic self-stiffened panels
First Claim
1. A composite panel comprising a first skin forming an outer wall of the panel, and a bottom face of said panel, and a second skin forming part of an inner wall of the panel, wherein the second skin is formed hollow to constitute an inner reinforcing frame forming at least one hollow-profile stiffener, this being provided with flanged edges for fixing to the first skin, with a face, forming a top face of said panel with connecting flanks between said edges and said top face, the frame of the second skin together with the first skin providing a monolithic self-stiffened panel and wherein the inner reinforcing frame produces a plurality of hollow-profile stiffeners distributed over a circumference of the panel, the frame including cutouts delimited by beam portions made by said hollow profile stiffeners.

Abstract
A composite panel having a first skin forming the outer wall of the panel, known as the lower face (1), and a second skin forming part of the inner wall of the panel. The second skin is formed hollow such as to produce an inner reinforcing frame (2) in the form of a half-box structure (3) which, together with the first skin, forms box parts. The aforementioned frame is equipped with a rim (4a, 4b) for fixing to the first skin, a face known as the upper face (5) and connecting side walls (6, 6a, 6b, 6c, 6d, 6e, 7) between the rim (4a, 4b) and the upper face (5) the first and second skins forming a monolithic self-stiffened panel. The half-box frame (2) has perforated sections (8) which are defined by hollow beam sections forming the half-box frame (2).
