Abstract
A method reinforcing an axisymmetric annular metal part by including a winding of composite material. A metal blank for the part is prepared, a cavity is formed therein that opens out into a coaxial inside face thereof, and that presents a right cross-section of axial extent that decreases from the inside towards the outside, a reinforcing yarn is wound in the cavity, the cavity is closed, the assembly is subjected to a hot isostatic compression process, and the blank is machined to obtain a final part.
Claims7
A method of fabricating an axisymmetric annular metal part reinforced by including coaxial annular reinforcement therein in a form of a winding of composite material, the method comprising:
- preparing an annular metal blank for the part;
- making or finishing off a cavity that opens out into a coaxial inside face of the blank and that possesses a right cross-section of axial extent that decreases going radially outwards over at least a portion of a height thereof;
- winding a reinforcing yarn in the cavity so as to fill substantially all of a space therein with a winding;
- closing the cavity by putting into place a metal cylindrical wall in register with an opening of the cavity so as to present an assembly;
- then
- subjecting the assembly to a hot isostatic compression process;
- and
- machining the blank to obtain a final shape of the part.
