Method for making a composite panel and composite panel obtained by said method

A composite panel, in particular for aircraft or nautical furniture, the composite panel comprising:

• a central core formed from a core of a low-density structured material type covered on its two faces with at least one layer of material preimpregnated with resin;
• and
• at least one a cladding which is prebaked with an adhesive film that forms a sealed barrier on one face of the cladding so that the sealed barrier seals the cladding from penetration of resin from the at least one layer of material preimpregnated with resin, into the cladding;
• wherein the adhesive film is disposed between the central core with the at least one layer of material preimpregnated with resin and the cladding so that the sealed barrier seals the cladding and prevents penetration of subsequent resin into the cladding.
