Process for producing a composite part composed of a fleece (10) and of a reinforcement comprising the stages consisting in:
- producing a profile (30) made of a fibrous structure stiffened by impregnation with a thermoformable binder, the profile having a cross-section corresponding to the dimensions of an uncompacted blank of the part to be produced with the fleece and the reinforcement when combined,
- machining a blank of the part to be produced in a length of the profile,
- forming the said blank in a press to obtain a preform having the shape and dimensions close to those of the part to be produced, and
- densifying the preform by vapour-phase infiltration of a material constituting a matrix within the fibrous texture, after removal of the thermoformable binder. |
