Abstract
A fitted platform for positioning between two adjacent blades of an aviation turbine engine fan includes a flow passage wall made of composite material having a central portion, and first and second margins each extending in a longitudinal direction of the wall. Each margin extends over a determined distance from the central portion in a transverse direction of the wall. The flow passage wall includes a fiber reinforcement densified by a matrix. The fiber reinforcement present in the central portion presents three-dimensional weaving, and the fiber reinforcement present in the first and second margins presents two-dimensional weaving, at least in part.
