METHOD FOR MANUFACTURING A COMPLEXLY SHAPED COMPOSITE MATERIAL PART

摘要

A part of complex shape made of composite material comprising three-dimensionally woven fiber reinforcement densified with a matrix is fabricated by a method comprising the steps of: .cndot. three-dimensionally weaving a continuous fiber strip comprising a succession of fiber blanks (200) for preforms of a plurality of parts that are to be fabricated; .cndot. subsequently cutting individual fiber blanks out from the strip, each blank (200) being a one-piece blank; .cndot. shaping a cut-out blank to obtain a one-piece fiber preform having a shape that is close to the shape of a part that is to be fabricated; consolidating the preform in the desired shape; and densifying the consolidated preform by forming a matrix by chemical vapor infiltration.
