Abstract

Procédé de fabrication d'au moins une pièce en matériau composite, le procédé comprenant les étapes successives suivantes : - prévoir un premier outil de formage (20) chauffé à une température supérieure à la température de fusion du matériau thermoplastique (13), - disposer au moins une couche de renfort et un matériau thermoplastique (13) dans le premier outil de formage (20) ; - fermer le premier outil de formage (20) et appliquer une première pression dans ledit premier outil de formage (20) ; - ouvrir le premier outil de formage (20) et transférer la pièce non-consolidée vers un deuxième outil de formage (22), ledit deuxième outil de formage (22) présentant une température inférieure à la température de fusion du matériau thermoplastique (13) ; - consolider la pièce non-consolidée puis sortir la pièce consolidée (46) du deuxième outil de formage (22).Method for manufacturing at least one part made of composite material, the method comprising the following successive steps: - providing a first forming tool (20) heated to a temperature above the melting point of the thermoplastic material (13), - placing at least one reinforcing layer and a thermoplastic material (13) in the first forming tool (20); - closing the first forming tool (20) and applying a first pressure in said first forming tool (20); - opening the first forming tool (20) and transferring the unconsolidated part to a second forming tool (22), said second forming tool (22) having a temperature below the melting point of the thermoplastic material (13) ; - consolidate the non-consolidated part then remove the consolidated part (46) from the second forming tool (22).
