Abstract
The invention relates to a process for manufacturing a sandwich panel comprising a step to bake a stacked structure () provided with: a honeycomb body (); a film () pre-impregnated with a first resin with a polymerization temperature T; and a first stack () of fiber layers pre-impregnated with a second resin with a polymerization temperature Tgreater than T, the film being arranged between the first stack and the body. The baking step comprises a first phase designed to use the film (), to create a rigid barrier providing a seal from the second resin by polymerization of said first resin, followed by a second phase designed to produce the skin starting from the stack (), by polymerization of the second resin.
