Abstract: Use of a benzoxazine resin (12) for the bonding of a monofilament (10) made of glass-resin composite including glass filaments (101) embedded in a thermosetting polyester resin (102), to a thermoplastic material (14), notably polyester; process for adhering such a monofilament to the thermoplastic material (14), including at least the following steps: —impregnating the monofilament (10) with a benzoxazine resin (12) in the liquid state; —after impregnation, heat-treating the monofilament (10) thus impregnated, so as to at least partly polymerize the benzoxazine resin (12); —depositing, onto the monofilament (10) thus adhesively coated, the thermoplastic material (14) in the molten state; —after cooling, optionally heat-treating the monofilament thus coated (R-1, R-2) to totally polymerize the benzoxazine resin (12) on contact with the thermoplastic material (14).

Abstract: A method for manufacturing a stator of an electrical rotating machine that is configured to have a rotor mounted inside the stator. The stator has a laminated magnetic circuit having a stack of magnetic metal sheets disposed substantially parallel to a plane perpendicular to the axis of rotation of the rotor of the machine. The magnetic circuit has teeth that delimit longitudinally oriented slots. The method includes the step of installing electrically conductive wires in the slots and forming winding heads at the two axial ends of the magnetic circuit and installing this assembly on a vertical axis. The assembly is trapped between an outer sheath, forming part of the final motor, and a removable inner core substantially occupying a volume reserved for the rotor. The conductive wires in the slots are impregnated under vacuum with a slot-impregnating composition including a heat-setting resin and a filler, and the composition is polymerized.

Abstract: A method is provided for manufacturing a stator of an electrical rotating machine. The method includes: impregnating a first winding head with a first composition that includes a heat-setting resin and a filler of a first particle size; impregnating conductive wires in a slot region with a slot-impregnating composition that includes a heat-setting resin and another filler of a second particle size smaller than the first particle size of the filler of the first composition; and impregnating a second winding head with a composition that includes a heat-setting resin and a filler of a particle size larger than the second particle size.

Abstract: A process for the production of a vulcanized elastomer composition, said process consisting in producing an aqueous dispersion containing at least latex with a small particle size and a filler having undergone a mechanical working stage and conventional vulcanization ingredients, in drying said dispersion and then vulcanizing it in a mould under pressure without subjecting said dried aqueous dispersion to mechanical working.

Abstract: The stator for an electrical machine comprises a laminated magnetic circuit 1 having a plurality of teeth delimiting longitudinally oriented slots, electrically conductive wires 2 being disposed in the slots, and winding heads 3 at the ends of the stator. An outer sheath 4 forms part of the final motor. The stator includes a composition 6 for impregnating the winding heads, of which the filler has a large particle size, and a slot-impregnating composition 8, containing a filler of smaller particle size.

Abstract: A process for making a composite product in which reinforcement fibers are subjected to a composition based on a thermohardening resin and a photoinitiator appropriate to the irradiation by which the composition is to be treated. The resulting pre-impregnated material is introduced into a prepolymerization device, in which the pre-impregnated material is prepolymerized by appropriate irradiation. Lengths of the precomposite are applied to a support, the shape of which is dictated by the shape of one face of the composite part which is to be made, and are stacked one on another in a suitable number and placed snugly against the shape of the support, and the stack is subjected to final molding at a suitable pressure and temperature in order to polymerize the resin and to join the different lengths of precomposite.
