The invention relates to a method for making a thermoplastic composite part by moulding, that comprises: making several portions of the part according to a moulding method that comprises placing in a mould a composite material containing fibres imbedded in a thermoplastic matrix while arranging the material so that the fibres contained therein are oriented along one or more preferred directions; submitting said mould to particular pressure and temperature conditions knowing that for each of the different portions, the fibres may be of different natures and dimensions and may be oriented in different directions while the thermoplastic matrix and that of the material used for making the first portion are identical or compatible; and assembling the different portions obtained, placing them in a mould, and submitting the latter to particular pressure and temperature conditions.

Procédé de fabrication par moulage d'une pièce composite thermoplastique qui consiste à : -réaliser plusieurs parties (1,2,3) de la pièce composite, au, travers d'un procédé de moulage consistant à mettre en place dans un moule un matériau composite constitué de fibres noyées dans une matrice thermoplastique, tout en arrangeant ledit matériau en sorte que les fibres qu'il comporte soient orientées selon une ou plusieurs directions préférentielles, puis à soumettre ledit moule à des conditions particulières de pression et de température, sachant que pour chacune des différentes parties les fibres sont susceptibles d'être de natures et de dimensions différentes, et orientées différemment, tandis que la matrice thermoplastique et celle du matériau utilisé pour fabriquer la première partie sont identiques ou compatibles, - puis assembler les différentes parties (1,2,3) obtenues, les introduire dans un moule, puis à soumettre ce dernier à des conditions particulières de pression et de température.
