Abstract: A door-type thrust reverser device for a turbojet engine nacelle is provided that includes a fixed structure, a mobile structure mobile with respect to said fixed structure, and at least one door mounted with the ability to pivot via pivots between a retracted position corresponding to the nacelle operating in direct-jet mode, and a deployed position corresponding to the nacelle operating in reverser-jet mode. The thrust reverser device includes a device for bleeding off some of a secondary or bypass airflow, which device is able to bleed off part of the secondary airflow from a duct through which the secondary airflow circulates and for conveying said bled-off airflow toward at least one pivot of the door, so as to cool areas on and/or around the door pivots.

Abstract: The invention relates to a method for making a part made of a composite material with a metal matrix, characterised in that the method includes the steps of: providing, on a preform of the part to be made, at least one assembly of reinforcing fibres, said fibres being previously coated with at least one metal or metal alloy; heating the assembly to a temperature sufficient for diffusing the metal particles surrounding the fibre; after cooling, releasing the part made of the preform and withdrawing the latter.
