Definitions

  • the present invention belongs to the field of the manufacture of parts made in part at least with a composite material comprising long fibers in a thermosetting organic matrix.

  • thermosetting prepreg materials In this category of composite material parts, long fiber ribbons pre-impregnated with resin to enter into the production of a part are initially worked, that is to say cut and shaped for example using a mold. hollow or raised. The resin that impregnates the fibers is not polymerized at a significant stage and generally has a pasty state at this stage. Ribbons of long fibers pre-impregnated, for example in webs or in woven form, then have no rigidity which allows them to marry closer to the shapes of the molds.
  • thermal baking according to a cycle adapted to the resin used, which has the effect of irreversibly hardening the resin by polymerization.
  • This thermal baking is generally carried out by applying a pressure on the part at certain stages of said baking in order to creep, before curing, the excess resin to obtain a fiber content as high as possible in the finished material constituting the piece and also to eliminate as much as possible traces of porosity.
  • the materials used are delivered to the workshops to ensure their shaping already prepregs, prepreg being itself a complex and specialized operation, and are kept at low temperatures to prevent them from hardening at room temperature before they are put implemented.
