摘要

A turbomachine vane (10) made from composite material comprises a hollow blade (12) including an internal passage (11) extending along the entire length thereof, an internal platform (14) and an external platform (16). The blade is extended on the external side of the external platform by an upstream attachment portion and a downstream attachment portion for mounting the vane in a casing, said attachment portions being formed by attachment lugs (24, 26, 28) extending from external longitudinal ends of lower surface (12a) and upper surface (12b) walls of the blade, with the fibrous reinforcement texture of the composite material extending continuously between said walls and the attachment lugs.
