METHOD AND DEVICE FOR MANUFACTURING A COMPOSITE PART BY DRAPE FORMING

摘要

The present disclosure relates to methods for manufacturing a part made from a composite material by means of a drape forming operation as well as to a tool for implementing the methods. In particular, the part has at least one inner convex surface. The methods use at least one outer manufacturing mold and at least one intermediate mold. The inner surface of the outer manufacturing mold substantially defines outer lines of the part to be manufactured, and the intermediate mold is arranged opposite the inner surface of the outer manufacturing mold such that an inner surface of the intermediate mold at least partially defines the molding lines of an intermediate portion of the part to be produced.

主权项

1. A method for manufacturing a part from composite material by a draping operation, said part having at least one convex inner surface, the method comprising:
disposing elements to make an outer portion of the part to be made on an inner surface of an outer manufacturing mold which defines at least in part lines of an outer surface of the part; making the outer portion of the part by a plies laying method and at least partial polymerization of a resin; installing an intermediate mold at a portion of an inner surface of the outer portion of the part, wherein an inner surface of the intermediate mold provides an interface with a remaining portion of the inner surface of the outer portion of the part, and defines at least in part, molding lines of an intermediate portion of the part to be made; disposing elements to make the intermediate portion and making the intermediate portion by draping operation and at least partial polymerization of the resin; and disposing on the intermediate portion, elements for a remaining inner portion to be made and making the remaining inner portion by draping operation and at least partial polymerization of the resin.
