Abstract: A process for mounting a metal part in a composite material part that belongs in particular to an aircraft subassembly, whereby the metal part includes at least one hollow portion and includes an inside wall that is identical in shape to its outside contour, whereby the inside wall and the outside contour are separated by the thickness of the portion, whereby the portion is pre-coated by glue and the composite material part includes at least one housing for receiving the inside profile that is a mirror image of the outside contour of the portion of the metal part, characterized in that the mounting process calls for ensuring an expansion of the inside wall of the portion that gives rise to an expansion of its outside contour and that determines the expansion forces applied by the portion against the wall of the housing.

Abstract: A process for mounting a metal part (10) in a composite material part (12) that belongs in particular to an aircraft subassembly, whereby the metal part (10) includes at least one hollow portion (16) and includes an inside wall (22) that is identical in shape to its outside contour (18), whereby the inside wall (22) and the outside contour (18) are separated by the thickness of the portion (16), whereby the portion (16) is pre-coated by glue and the composite material part (12) includes at least one housing (14) for receiving the inside profile (20) that is a mirror image of the outside contour (18) of the portion (16) of the metal part (10), characterized in that the mounting process calls for ensuring an expansion of the inside wall (22) of the portion (16) that gives rise to an expansion of its outside contour and that determines the expansion forces applied by the portion (16) against the wall of the housing (14).
