| description | A method for manufacturing a part made of composite material comprising a reinforcement made up of fibers impregnated with a resin matrix, comprising the steps of laying dry fibers flat and covering the dry fibers on a flat surface of a laying tool, infusing flat dry fibers with the resin; forming the dry fibers on a counter-mold, a first polymerization at a first polymerization temperature, the first polymerization being undertaken to obtain 20% to 30% hardening of the resin to obtain an intermediate reinforcement, the first polymerization being subsequent to the steps of infusing and of forming, demolding and machining the intermediate reinforcement, a second polymerization of the machined intermediate reinforcement at a second polymerization temperature, the value of the second temperature being greater than the value of the first temperature. |
