Abstract: A method for producing casing for an aircraft turbine engine includes a first step of manufacturing an annular shell having an axis A made of a composite material in a mold that includes an annular cavity that receives the preform. A resin is injected into the cavity and subsequently polymerized. During a second step, at least one axial abutment means is arranged inside the shell, and during a third step, the annular cartridge made of an abradable material is arranged inside the annular shell in contact with the axial abutment means. A fourth step includes bonding the annular cartridge to the first inner annular surface. The first and second steps are simultaneous, and the at least one axial abutment means is molded with the preform in the mold.

Abstract: A tool for forming an abradable coating in an aircraft turbine engine module, this module having an annular stator casing and a central rotor which can move inside the casing about an axis, wherein it has a first portion which is attached to the rotor, a second portion which includes at least one first trans-verse arm extending radially outwards and carrying spreading rollers, and a flywheel centered on the axis and configured to be rotated manually by an operator in order to rotate the tool and the rotor within the casing, so that the spreading rollers are capable of spreading a resin in order to form the coating.
