  • Patent number: 10092928
    Abstract: A process of manufacturing component with a composite film including a matrix made of thermoplastic polymer and particles inside this matrix. This process includes heating the composite film in order for its temperature to exceed the glass transition temperature of its matrix, then when the composite film is softened, flattening an external face of the composite film by a smooth face resting directly over the whole of this external face, this smooth face forming part of the front face of a flexible membrane, the whole of the rear face of which, located on the side opposite the front face, is pushed against the composite film by a fluid, then cooling the composite film below the glass transition temperature, then withdrawing the membrane in order to mechanically separate its front face from the external face of the composite film.
    Type: Grant

  • Patent number: 9676173
    Abstract: Process for the transfer of a composite film onto a flexible polymer membrane in which the composite film comprises a matrix made of thermoplastic polymer and particles. This process comprises the following operations: 1) the movement of the membrane into a position in which it closes up, in a way leaktight to a fluid, an opening of a reservoir and a first zone of its front face is directly in contact on an external face of the composite film, 2) the heating of the composite film, so as to soften it, then 3) when the composite film is softened, a fluid inside the reservoir uniformly compresses the first zone against the external face of the composite film in order to adhesively bond this first zone to this external face, then 4) the movement of the membrane to a retracted position in order to separate, from the rigid substrate, the portion of the composite film adhesively bonded to the first zone.
