COMPACTING ASSEMBLY AND METHOD OF FABRICATING A COMPOSITE BLADE FOR A TURBINE ENGINE

摘要

Compacting assembly comprising a shaper mold (24) defining an upwardly open housing suitable for receiving a woven preform (10a) that has previously been cut out, and a vertically movable compacting tool (128) that, together with the shaper mold (24), forms a compacting assembly for compacting said preform previously placed in the housing. The compacting tool (128) comprises at least a root portion (128A). The invention is applicable to fabricating turbine engine composite blades.

1. A compacting assembly for compacting a woven preform obtained by three-dimensionally weaving yarns in order to form a composite blade for a turbine engine, said preform having portions for predefining the airfoil, the root of the blade, and between the airfoil and the root, the tang of the blade, the compacting assembly comprising a shaper mold defining an upwardly open housing suitable for receiving a woven preform, and a vertically movable compacting tool for co-operating with the shaper mold to form a compacting assembly enabling said preform to be compacted when it is placed in the housing, wherein the compacting tool comprises at least a root portion, further comprising a deformable skin covering at least part of the compacting tool facing the sharper mold.
