REINFORCEMENT FOR A COMPOSITE BLADE OF A TURBOMACHINE, COMPRISING A STACK OF PLIES

Abstract: the present application relates to a reinforcement () for a blade () of a turbomachine (), the blade () comprising a first outer skin () and a second outer skin () which are made of composite material and each comprise an inner end portion () spaced apart from each other in such a way as to delimit therebetween an inner cavity () of the blade () that opens into an opening (), wherein the reinforcement () is adapted to be arranged in the inner cavity () in such a way as to close the opening (), and wherein the reinforcement () comprises a stack of plies () that are superposed along a stacking direction (de) corresponding to a thickness direction (pe) of the plies (), at least two plies () having different lengths (pl) and/or widths (pl) such that the reinforcement () has a profile of variable dimensions.
