Abstract: The invention relates to a resin injection regulator for a resin injection circuit in a mould for producing a composite part, in particular a turbine engine composite part, characterised in that it comprises at least one vessel which is connected to said circuit and inside of which a movable wall means can be moved in a sealed manner, said movable wall means defining in said vessel a first cavity which forms a container for accumulation of resin and is designed to be connected to at least one part of said circuit, and a second cavity which is designed to be connected to a source of pressurised fluid, said movable wall means being designed to be urged by the pressurised fluid with which the second cavity is supplied in order to exert a pressure on the resin contained in the first cavity by isolating said resin from said fluid.

Abstract: The invention relates to a method of repairing a blade (1) made of composite material, extending in a so-called axial direction (X), the said blade (1) comprising a root (2) and a blade (3), the axial end of which opposite the root (2) comprises an area to be repaired, the said blade (3) comprising an intrados (4) surface and an extrados (5) surface.

Abstract: The invention relates to a method for manufacturing a carrying casing (12) provided with a collar (18) for supporting at least one cartridge of abradable material for a turbomachine, said carrying casing (12) comprising at least one bare annular casing (16) and one block of honeycomb material (20) that comprises an outer face (22) configured to be secured to an inner face (24) of said bare annular casing (16), said block being covered with a skin (26), characterized in that it comprises successively: —a step in which the outer face (22) of the block (20) is secured to the inner face (24) of the bare annular casing (16), —a step in which the circularity of San inner face (32) of the block (20) is monitored and in which, if necessary, the inner face (32) of the block (20) is machined to round, —a step in which, simultaneously, said skin (26) is produced and is secured to said block (20).

Abstract: A method of fabricating a woven fiber preform that is impregnated with a matrix-precursor resin, the resin, in the raw state, presenting a glass transition temperature Tg0, includes: impregnating yarns or strands with the resin; feeding a loom with the impregnated yarns or strands maintained at a temperature in the range Tg0 to Tg0+10° C.; and weaving the yarns or strands in the loom in order to obtain the resin-impregnated woven fiber preform.

Abstract: A method for manufacturing a panel for supporting at least one cartridge of abradable material for a turbine engine casing, the panel including at least one block of material and a rigid panel covering the at least one block of material, except for a free outer surface configured to be fixed to an inner surface of the casing, including: a step of machining the outer surface of the block of material according to a three-dimensional profile configured to match that of the inner surface of the casing, and a step of fixing the machined block to the rigid panel.

Abstract: The invention relates to a method for manufacturing a panel for supporting at least one cartridge of abradable material for a turbine engine casing, said panel including at least one block of honeycomb material covered with a rigid skin, characterised in that it includes: a step of machining (ET5?) an outer surface of a block of material, in particular a honeycomb material, according to a three-dimensional profile configured to match that of an inner surface of the casing; and then, a step (ET6?) of adhering the block of machined material to the rigid skin.

Abstract: A method for producing a part by injecting resin into a woven fiber preform includes the steps of (a) shaping the preform, (b) forming the preform, and (c) injecting resin into the preform. The step of injecting resin into the preform is carried out by means of equipment that includes a mold, a countermold, and resin injecting means. The step of injecting resin into the preform includes the substeps of: partially opening the equipment, injecting resin into the equipment, closing the equipment, and pressurizing and heating the impregnated preform between the mold and the countermold.
