The process for making a multi-layer panel consists of applying a first ( 3 ) and second ( 4 ) fibre-based material on the opposite faces of a core ( 2 ) of the panel ( 1 ), joining the first and second material through a needling operation through the thickness of the core, carrying out the impregnation of the first and second fibre-based material with a resin-based material and introducing the resin-based material inside the needling holes ( 6 ) for their entire extension, and polymerising the resin-based material so that at least the polymerised resin-based material present in the needling holes defines a plurality of structural rigidifying elements ( 5 ) that connect the first and second fibre-based material. |
