Abstract

L'invention concerne un boitier auto-raidi (1) comportant une peau de base tridimensionnelle (10) en matériau composite stratifié, conformée selon des parois (F1 à F5) formant sensiblement un parallélépipède rectangle ouvert sur une face (F6) et s'étendant selon un axe longitudinal (X'X). Sur cette peau de base (10) est drapé au moins un ensemble de résistance mécanique comprenant une couche de renfort constituée de portions de nappes (21 à 27) agencées en treillis (2, 2') et recouverte d'une couche de peau stratifiée (30; 40) en matériau composite s'étendant sur le parallélépipède. Les nappes de renfort (21 à 27) sont en matériau composite à fibres unidirectionnelles et s'étendant sur les parois (F1 à F5) parallèlement ou perpendiculairement à un plan longitudinal (PL) contenant l'axe longitudinal (X'X) sans napper la face ouverte (F6).The invention relates to a self-stiffened box (1) comprising a three-dimensional base skin (10) of laminated composite material, shaped along walls (F1 to F5) forming substantially a rectangular parallelepiped open on one face (F6) and s' extending along a longitudinal axis (X'X). On this base skin (10) is draped at least one set of mechanical strength comprising a reinforcing layer consisting of portions of plies (21 to 27) arranged in lattice (2, 2 ') and covered with a layer of laminated skin (30; 40) of composite material extending over the parallelepiped. The reinforcing plies (21 to 27) are made of composite material with unidirectional fibers and extending on the walls (F1 to F5) parallel to or perpendicular to a longitudinal plane (PL) containing the longitudinal axis (X'X) without coating. the open face (F6).
