摘要：
The invention relates to a process for manufacturing a sandwich panel comprising a step to bake a stacked structure (16) provided with: a honeycomb body (2); a film (12) pre-impregnated with a first resin with a polymerisation temperature T1; and a first stack (18) of fibre layers pre-impregnated with a second resin with a polymerisation temperature T2 greater than T1, the film being arranged between the first stack and the body. The baking step comprises a first phase designed to use the film (12), to create a rigid barrier providing a seal from the second resin by polymerisation of said first resin, followed by a second phase designed to produce the skin starting from the stack (18), by polymerisation of the second resin.
