Abstract
A composite platform for a fan of an aircraft turbine engine. The platform includes an elongate wall and is configured to extend between two fan blades. The wall includes an aerodynamic outer surface and an inner surface, on which a fastening tab is located, wherein the fastening tab is configured to be attached to a fan disc. The fastening tab is integrally formed with a metal reinforcement which has a plate having an elongate shape and which extends over more than 50% of the longitudinal extent of the wall, the wall being produced by overmolding a resin on the plate so as to be integrated into the wall.
Claims15
A composite platform for a fan of an aircraft turbine engine, said composite platform comprising:
- a wall of elongated shape and configured to extend between two fan vanes, the wall comprising an aerodynamic external face and an internal face, the wall having a first longitudinal dimension;
- a metallic framework configured to be attached to a fan disc;
- the metallic framework formed of a single part including:
- a first portion forming an attachment tab;
- a second portion forming a plate, said plate having an elongated shape and a second longitudinal dimension which represents at least 50% of said first longitudinal dimension and at most 100% of said first longitudinal dimension,
- wherein said wall is produced by over-moulding a resin onto said plate such that the wall wraps around the plate, and wherein the attachment tab extends inwardly from the wall.
