Method for producing a solid part
View Patent ↗A method for producing a solid part, including weaving a three-dimensional fibrous structure, the weaving being carried out with metal braids consisting of a plurality of metal strands mutually twisted about the longitudinal axis of the braid; and performing hot isostatic pressing on the fibrous structure causing the agglomeration of the metal braids of the fibrous structure so as to produce a solid part.
1. A method of production of a solid part, said method comprising:
weaving a three-dimensional fibrous structure, said weaving being carried out with metal strands formed by a plurality of metal ends mutually twisted about the longitudinal axis of the strand;
performing hot isostatic pressing on said fibrous structure causing the agglomeration of the metal strands of said fibrous structure so as to produce a solid part.
2. The method of production according to claim 1 , wherein said weaving is carried out with metal strands formed by a plurality of metal ends, wherein the diameter of each end is less than 0.1 mm.
3. The method of production according to claim 1 , wherein said weaving is carried out with metal strands having a diameter equal to or greater than 0.5 mm.
4. The method of production according to claim 1 , wherein said weaving is carried out with metal strands having a diameter equal to or greater than 1 mm.
5. The method of production according to claim 1 , wherein said weaving is carried out with metal strands formed by a plurality of metal ends of titanium or by a plurality of metal ends of different materials.
6. The method of production according to claim 1 wherein said weaving is carried out with metal strands formed by a plurality of metal ends of different diameters.
7. The method of production according to claim 1 , wherein, prior to said hot isostatic pressing, said method comprises shaping said fibrous structure, said shaping being carried out manually.
8. The method of production according to claim 7 , wherein said shaping of said fibrous structure is carried out when said fibrous structure is put into place in a tool.
9. The method of production according to claim 1 , wherein, prior to said hot isostatic pressing, said method comprises cleaning said fibrous structure.
10. The method of production according to claim 1 , wherein said solid part is a metal reinforcement of the leading edge or trailing edge of the fan blade of a turbine engine or propeller.
11. The method of production according to claim 1 , wherein said method comprises:
weaving at least two three-dimensional fibrous structures, said weaving being carried out with metal strands formed by a plurality of metal ends mutually twisted about the longitudinal axis of the strand;
performing hot isostatic pressing on said at least two three-dimensional fibrous structures causing the agglomeration of the metal strands of said fibrous structures so as to produce a solid part.
