Method for making a thermoplastic composite part by molding

Method for making a thermoplastic composite part by molding, the method comprising the steps of:

• making a portion of the composite part, the composite part being formed by a molding method, said molding method being comprised of:
• placing, in a mold, a composite material comprised of fibers embedded in a thermoplastic matrix, while arranging said composite material so that the fibers contained therein are oriented along one or more preferred directions, and submitting said mold to particular pressure and temperature conditions;
• making at least a second portion of the composite part, the second portion being formed by a molding method, said molding method being comprised of:
• placing, in a mold, either a composite material comprised of fibers embedded in a thermoplastic matrix, while arranging said composite material so that the fibers contained therein are oriented along one or more preferred directions, or a material comprised of said thermoplastic matrix, and submitting said mold to particular pressure and temperature conditions, each different portion of fibers, when they contain such, are capable of being of different natures and dimensions, and may be oriented in different directions, as well as be in different proportions, whereas the thermoplastic matrix and that of the material used for making the first portion are identical or compatible;
• and
• assembling the different portions obtained, introducing them into a mold, then submitting the latter to particular pressure and temperature conditions.
