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.
