Abstract: A process for manufacturing a blade made of composite material for a turbomachine. The blade includes an airfoil having a pressure side and a suction side which extend from a leading edge to a trailing edge of the airfoil. The blade further includes a metal sheath that extends along the leading edge of the airfoil. The process includes the steps of: placing a preform, produced by three-dimensionally weaving fibers, in a mold, the sheath being positioned on an edge of the preform intended to form the leading edge of the airfoil; and injecting polymerizable resin into the mold to impregnate the preform so as to form the airfoil after solidifying. At least one double-sided adhesive film may be inserted between the sheath and the edge of the preform prior to injection of the resin.

Abstract: Method for forming a riblet on a component and riblet mould. This invention relates to a method for forming a riblet (3) on a component (1), characterised in that it comprises steps of: printing (106) the riblet on the component (1), comprising applying a film (1) comprising a riblet imprint (6) on the component (1), and peeling (108) the film (4) so as to separate the riblet imprint (6) from the component (1), after printing (106). This invention also relates to a riblet mould (3), the mould comprising a film (4) in which a riblet imprint (6) is formed, the film (4) being adapted to be separated from a component (1) on which a riblet (3) has been printed by means of the riblet mould (3), by peeling the film (4).
