L'invention est relative à une aube de turbomachine, comprenant un noyau central (1) recouvert par une pluralité de nappes de matériau composite. Selon l'invention, lesdites nappes (3) sont traversées par un réseau de coutures transversales (5). Une application est la réalisation d'aubages de grands diamètres. A gas turbine blade includes a central core covered by a plurality of layers of composite material, and optionally also an outer sleeve of woven composite material. A network of transverse seams pass through the layers of composite material, and preferably also the core and the outer sleeve. This construction is particularly applicable to large diameter turbine blades.
