摘要:
The invention concerns a method for producing a composite part having a continuous fibrous reinforcement and a polymer matrix from a composite preform, characterised in that it comprises a step consisting of: i. depositing a defined layer (110, 120) of a thermoplastic polymer on one of the faces of the preform (100), by an additive production method.

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.

Laminated composite structural panel with fibrous reinforcement comprising: a. a skin (101) of thickness e1, made up of a stack of fibrous plies in a matrix made of a thermoplastic polymer; b. a localized reinforcement or patch (102), connected to the surface of said skin (101) and rising up by a thickness e2 in a direction locally normal to the skin, made up of a stack of fibrous plies in a matrix made up of a thermoplastic polymer; c. the surface area of the plies that make up said patch decreases from the ply of the patch (102) that is in contact with the skin (101), such that the edges of said patch (102) are inclined by a slope p greater than 0.5 and such that the connection between the patch (102) and the skin (101) consists in a weld.

The invention relates to a stiffened panel (100) including: a) a laminated skin (110) extending in two direction and consisting of a resin and a continuous fibrous reinforcement; b) a first profiled stiffener (110) consisting of a resin reinforced by a continuous fibrous reinforcement, said first stiffener extending over a first surface of said skin (110) in a first direction; and c) a second profiled stiffener (130) consisting of a resin reinforced by a continuous fibrous reinforcement, said second stiffener extending over a second surface of said skin (110) in a second direction; d) wherein the resins constituting the skin (110) and the stiffeners (120, 130) are thermoplastic and said stiffeners (120, 130) are closely connected to the skin (110) by a weld. The invention further relates to an advantageous method for creating such a panel.

The invention relates to a panel (750), particularly for an aircraft floor, characterized in that it includes: a) a first plate (220) made of a composite material reinforced with continuous fibers; b) a corrugated sheet (730) made of a composite material reinforced with continuous fibers, which is coupled to a so-called lower surface of the first plate (220); and c) a local reinforcement means (751, 753, 752) which is coupled to the corrugated sheet (730).
