摘要:
The invention relates to a method for creating a structural element comprising a panel (110, 121, 122) made of a composite material having a fibrous reinforcement in an organic matrix obtained by layup and curing, which panel comprises a face liable to be exposed to contact with hydrocarbons, characterized in that it comprises the steps involving: a. laying up the plies of fibres preimpregnated with a resin that has a first curing temperature, T1, so as to obtain the desired layering effect; b. applying to the face that is exposed to the hydrocarbons a ply consisting of a thin film (130, 131, 132) of a polymer that is resistant to hydrocarbons and able to withstand the curing temperature T1, referred to as the protective film (130, 131, 132); c. curing the entire layered structure under pressure at the temperature T1.

The present invention relates to a composite material panel (1) comprising a composite material skin (2) having two generally opposite surfaces (20, 21) and first stiffeners (30) extending over one of the surfaces (20) of the skin. Said panel is characterized in that it comprises supplementary stiffeners (31) that are arranged on the surface (21) of the skin opposite the one having the first stiffeners (30), said supplementary stiffeners moreover extending in a direction separate from that of the first stiffeners (30). The skin and the stiffeners arranged on each surface are preferably secured to each other by means of co-molding.

The invention relates to a method for assembling a skin (102) and the flange of a stiffener, characterized in that it involves the steps consisting in: a. sealing the periphery of the contact between the skin and the flange of the stiffener by applying a bead (210, 211) of adhesive to the flange of the stiffener in contact with the skin; b. creating a first and a second orifice, known as vent orifices, in the skin, said orifices opening at the interface between the skin and the flange of the stiffener; c. injecting adhesive through the first orifice termed the injection orifice at the interface between the skin and the flange of the stiffener while keeping said skin in contact with the stiffener until adhesive has fully filled the interface between the skin and the stiffener.
