tissu de drainage Explanation: "La filière composite à l'Aérospatiale - w3architect.com http://www.w3architect.com/static/people/.../these/Aa-Filier... Les matériaux composites sont de plus en plus utilisés dans l'aéronautique car ... Elles offrent enfin l'intéressante capacité à pouvoir se réparer assez facilement. ... il est nécessaire d'interposer un tissu de drainage entre la pièce et la vessie, ..." "Vacuum Bag Materials Repairs of composite aircraft components are often performed with a technique known as vacuum bagging. A plastic bag is sealed around the repair area. Air is then removed from the bag, which allows repair plies to be drawn together with no air trapped in between. Atmospheric pressure bears on the repair and a strong, secure bond is created. Several processing materials are used for vacuum bagging a part. These materials do not become part of the repair and are discarded after the repair process. Bleeder Ply The bleeder ply creates a path for the air and volatiles to escape from the repair. Excess resin is collected in the bleeder. Bleeder material could be made of a layer of fiberglass, nonwoven polyester, or it could be a perforated Teflon® coated material. The structural repair manual (SRM) indicates what type and how many plies of bleeder are required. As a general rule, the thicker the laminate, the more bleeder plies are required." |
