Abstract: An integrated device for monitoring an electrically insulating part, the device having an optic fiber that includes at least one Bragg grating, the electrically insulating part being a composite material with a thermosetting matrix, and the optic fiber including a polyimide mechanical protection sleeve made. The device is integrated into an electrically insulating part or an electrically insulating enclosure. The invention also includes a method for manufacturing the device including positioning in a mold part of an optic fiber that includes at least one Bragg grating, and molding of the electrically insulating part.

Abstract: A thermoelectric module comprising a matrix comprising junctions having two N-type and P-type thermoelectric chips, said junctions being electrically connected to form an electric circuit. Flow of an electric current in the circuit heats one surface of the matrix by Peltier effect. Heating of one surface of the matrix makes an electric current flow by Seebeck effect. The module comprises a first group of junctions of two N-type and P-type thermoelectric chips exposed to a first operating temperature. A second group of junctions of two N-type and P-type thermoelectric chips is exposed to a second operating temperature. The second temperature is lower than the first temperature and the two groups of junctions are separated by a thermal insulator.

Abstract: An integrated device for monitoring an electrically insulating part comprising an optic fiber in which at least one Bragg grating is formed, the electrically insulating part being made from a composite material with a thermosetting matrix, and the optic fiber comprising a mechanical protection sleeve made from polyimide material. An electrically insulating part or an electrically insulating enclosure in which the foregoing device is integrated. A method for manufacturing the foregoing device comprising positioning of a part of an optic fiber in which at least one Bragg grating is formed in a mold to form the electrically insulating part, and molding of the electrically insulating part.

Abstract: A composite composition for injection moulding comprising: an organic matrix, between 5 and 15% in weight of reinforcing fibers, and solid particles comprising more than 5% in weight of beads and fire-resistant mineral particles 50% in weight whereof present a distribution function of equivalent diameters comprising at least two modes. A method for producing 100 parts in weight of the composition comprising: preparation of an organic matrix, adding and mixing of 5 to 15 parts in weight of reinforcing fibers, and adding and mixing of solid particles comprising fire-resistant mineral particles and more than 5 parts in weight of beads. A part obtained by injection and by moulding of the composition.
