Abstract: The invention relates to a method for making a thermoplastic composite part by molding. The method includes making several portions of the part according to a molding method, the molding method including placing, in a mold, a composite material containing fibers embedded in a thermoplastic matrix, while arranging the material so that the fibers contained therein are oriented along one or more preferred directions; submitting the mold to particular pressure and temperature conditions, knowing that for each of the different portions the fibers 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 mold, and submitting the latter to particular pressure and temperature conditions.

Abstract: The process includes placing in a mold a pile of plies taken from a web of fibers embedded in a thermosetting or thermoplastic material, the plies being arranged according to preferred directions of the fibers, and subjecting the mold to particular pressure and temperature conditions. The process also includes carrying out successive operations of shaping the pile of plies in the mold, at low pressure, carried out progressively at low speed; removing the material in excess protruding out of edge of the mold; carrying out the tightness of the mold from outside; increasing the pressure up to high pressure; raising the temperature of the mold; and quickly cooling the mold.
