Abstract: A part comprising a body and a film bonded to a surface of the body and incorporating an electronic circuit. This electronic circuit comprises at least one electronic component, conductive lines connected to the electronic component and at least two connection terminals positioned on at least one of the conductive lines, each connection terminal having a cross-section, in a plane parallel to the surface of the body, greater than twice the cross-section of a conductive line. By virtue of the connection terminals, which are distributed over the electronic circuit, it is possible to replace a faulty circuit segment with a repair circuit segment.

Abstract: A method for assembling two parts, referred to as first and second parts, the first part being produced from composite material with fibrous reinforcement embedded in a thermosetting or thermoplastic matrix, the method comprising the steps of: obtaining the first part comprising, on all or part of an outer surface, a first amorphous thermoplastic film; positioning the first part and the second part such that the first amorphous thermoplastic film is placed opposite the second part; introducing a thermosetting resin between the first amorphous thermoplastic film and the second part; at least partially polymerising the thermosetting resin. When the two parts comprise an amorphous thermoplastic film, the parts are positioned such that the respective amorphous thermoplastic films are placed opposite each other, and the thermosetting resin is introduced between the amorphous thermoplastic films.

Abstract: A method for creating a structural part made of composite material by injecting-infusing a liquid, thermosetting resin into a fibrous reinforcement, the structural part comprising a first element and at least one second element. Both the first element and the at least one second element are created in an intermediate state during a distinct injection-infusion step associated with partial curing that is arrested at a degree of cross-linking of the resin below a gelling point of the resin. The first element and the at least one second element are held in a tooling, in a relative position and in a shape that the elements are to have in the structural part to be created, during an out-of-autoclave simultaneous complete curing phase so as to obtain a desired degree of polymerization of the resin of the first element and of the resin of the at least one second element.

Abstract: A process for fabricating a partially polymerized prepreg material. Fibers are impregnated with thermosetting resin. The resin is partially polymerized to a degree of polymerization between 10% and 60%. The thermosetting composite parts are produced by drape forming of the prepreg material. The material laid-up in the form of tapes and heated at a temperature above the glass transition temperature of the prepreg state. The laid-up material is pressed and cooled to return the laid-up material to a temperature below the glass transition temperature of the prepreg state in question.

The resin is partially polymerized to a degree of polymerization between 10% and 60%. The thermosetting composite parts are produced by placement of fibers of the prepreg material. The material is laid-up in the form of rovings and heated at a temperature above the glass transition temperature of the prepreg state. The laid-up material is pressed and cooled to return to a temperature below the glass transition temperature of the prepreg state. The temperatures and the pressure are determined so that the part obtained has a void content of less than 4% by volume.

Abstract: A metallization ply (1) for the metallization of a thermoplastic composite material part (3), includes in the body thereof at least one substantially continuous metal layer (10) and at least one binding layer (11) secured to the metal layer and realized with a thermoplastic resin. A manufacturing method for a metallized thermoplastic composite material part (3) includes i) a step in which a structural ply or plies (20) are deposited forming a structural layer (2) of the part, ii) a step in which the metallization ply (1) is deposited on an outer face (2a) of the structural layer (2) with the binding layer (11) on the side of the outer face (2a) of the structural layer (2), and iii) a step in which the metallization ply (1) is consolidated with the structural layer (2). A metallized thermoplastic composite material part (3) is also described.

Abstract: To manufacture a piece made of composite material with thermosetting matrix, at least one element of the piece is manufactured separately based on strips of fibers preimpregnated with thermosetting resin, which element is subject to a partial thermal curing, having the effect of partially polymerizing the resin of the first element, on the one hand, up to a stage in which the first element has acquired both a sufficient chemical stability to guarantee its storage at ambient temperature and a sufficient dimensional stability to ensure its handling and to guarantee its integrity during later manufacturing operations of the piece and, on the other hand, limited to a stage in which the material forming first element has thermoplastic properties making possible a plastic forming of the first element by raising its temperature at least locally.
