Abstract
The invention relates to a multilayer device for a mould having a surface layer and at least one reinforcing layer made of composite material coated with a thermosetting material. The surface layer includes a functional face of complex shape constituting a negative of a composite part to be manufactured. The multilayer device further includes at least one first heating network configured to heat the functional face and to implement a thermal treatment surface for the composite part and at least one second heating network configured to heat the surface layer around the functional face and to define at least one thermal blocking belt at the at least one periphery of the thermal treatment surface.
