The invention relates to a method for producing panels (9) for aeronautical structures with U-shaped stiffening elements (13) and I-shaped reinforcing elements (17) which are disposed between the arms of the U-shaped elements. The inventive method comprises the following steps consisting in: obtaining laminates which are to be used to form the skin (11) on the curing tool (31); obtaining flat laminates (23) which are to be used to form the stiffening elements (13, 17); forming the U-shaped elements (13) on individual tools (33) and positioning the I-shaped elements (17) on said tools (33); grouping the individual tools (33) together on a single tool (41); positioning all of the stiffening elements (13, 17) on the skin (11); positioning a vacuum bag (55) over the assembly with the aid of profiles (59); and strengthening the assembly by performing a curing process under suitable pressure and temperature conditions, using external tools (60) in order to ensure that the arms of the stiffening elements (13, 17) are vertical.

L'invention concerne un procédé de fabrication de panneaux (9) destinés à des structures aéronautiques, dans lequel sont utilisés des éléments de rigidité en forme de U (13) et des éléments de rigidité et de renfort en forme de I (17) entre les ailes. Ce procédé consiste à utiliser des stratifiés pour adapter la peau (11) à l'outil de durcissement (31), à utiliser des stratifiés plats (23) pour adapter les éléments de rigidité (13, 17), à adapter les éléments en forme de U (13) aux outils individuels (33) et à disposer les éléments en forme de I (17) sur lesdits outils (33), à regrouper lesdits outils individuels (33) sur l'outil formant un ensemble (41), à disposer l'ensemble d'éléments de rigidité (13, 17) sur la peau (11), à disposer un poche à vide (55) sur l'ensemble à l'aide de profilés (59), et à consolider ledit ensemble moyennant un procédé de durcissement, dans des conditions adaptées de pression et de température, au moyen d'outils externes (60), afin de garantir la verticalité des âmes des éléments de rigidité (13, 17).
