Abstract
The invention relates to a method for manufacturing a turbine engine blade from a preform (10) of composite material polymerised in a mould comprising a lower part (16) and an upper part, comprising at least one closure step, during which the upper part of said mould is placed on the lower part (16) of the mould containing the preform (10). The method comprises, prior to said closure step, at least one sub-step of inserting a position marker (28) into the preform (10), at least one sub-step of compacting the preform using an insert (34) intended to be received in the upper part of the mould (18), and at least one sub-step of checking the position of the marker (28) relative to a reference mark (30) of said insert (34).
