Abstract
A turbomachine blade, particularly a fan blade for an aircraft jet engine, is made of a composite material comprising reinforcing fibres embedded in a thermosetting resin matrix, wherein the reinforcing fibres form a multilayer woven fabric in which the warp fibres of each layer are interwoven not only with the weft fibres of the layer but also with the weft fibres of at least the layers immediately above and below it so that the layers are all interconnected. Also, each layer only partly covers the layer below it so that the ends of the warp and weft fibres of a layer extend to near the surface of the blade, and the thickness of the blade at any point is determined by the number of layers present at that point.
