Abstract
A process relating to the manufacture of a composite component comprising a web and a reinforcement structure. The process includes providing a profiled section constituting a fibrous structure that is rigidified by impregnation with a thermoformable binder. The profiled section provided has a cross-section corresponding to the dimensions of a non-compacted blank of the component to be formed in a single unit with the web and the reinforcement structure. A blank of the component to be produced is machined from a length of the profiled section. The blank is press formed to obtain a preform having a shape and dimensions approximating those of the component to be produced and the preform is densified by chemical vapor infiltration of a material constituting a matrix within the fibrous structure, after elimination of the thermoformable binder.
