METHOD FOR SHAPING A FILM OF A MATERIAL THAT HAS LOW RESISTANCE TO TRACTION, AND MIRROR COMPRISING SUCH A FILM

摘要

The invention relates to a method for shaping a film of glass having a thickness Ev, said method comprising: a step (310) of applying and adhering a layer of a first material that can be subjected to traction to a first face of the film of glass, said layer having a thickness E1 such that: either the neutral fibre of the complex moves across into the layer of said first material, the glass being then completely under compression, or the neutral fibre moves towards said first material but remains in the glass film, the surface of the glass being then subjected to a level of traction lower than the rupture value; a step (320) of deforming the complex comprising the film of glass coated with the first layer of material, such that it is close to the final shape, in such way that the glass is mainly under compression; a step (330) of applying a stabilising element B; and a step (340) of adhering or attaching the stabilising element B to the complex A and of dimensional stabilisation of the final shape.
