A method of laying up a thermoplastic composite in a mould tool (1), the method comprising: providing a mould tool having a mould surface (3), at least a portion of the mould tool comprising a porous material; applying a negative pressure to the porous material (5) so as to create a negative pressure at the mould surface; laying an initial layer (8) of thermoplastic compos-ite material onto the mould surface, whereby the thermoplastic composite material is held against the mould surface by virtue of the negative pressure at the mould surface; and consolidating the thermoplastic composite material.
L'invention porte sur un procédé consistant à poser un composite thermoplastique dans un outil de moule (1), le procédé comprenant les opérations consistant à : disposer un outil de moule pourvu dune surface de moule (3), au moins une partie de l'outil de moule comprenant un matériau poreux; appliquer une pression négative au matériau poreux (5) de façon à créer une pression négative au niveau de la surface de moule; poser une couche initiale (8) de matériau composite thermoplastique sur la surface de moule, ce par quoi le matériau composite thermoplastique est maintenu contre la surface de moule grâce à la pression négative au niveau de la surface de moule; et consolider le matériau composite thermoplastique.
