Mechanical component comprising an insert made of composite
View Patent ↗A method of manufacturing a mechanical component, a mechanical component thus obtained, and a winding device designed for implementing the method of manufacture. The mechanical component includes at least one insert made of metal matrix composite, within which matrix ceramic fibers extend, the composite insert being obtained from a plurality of coated filaments each including a ceramic fiber coated with a metal sheath, the method including manufacturing at least one insert by winding a bonded lap or bundle of coated filaments about a component of revolution. At least some of the winding is performed in a rectilinear direction.
1. A mechanical component comprising:
at least one insert made of metal matrix composite, within which insert matrix ceramic fibers extend, the composite insert being obtained from a plurality of coated filaments each comprising a ceramic fiber coated with a metal sheath, the insert being part of the mechanical component,
wherein the insert has a geometry of revolution including two rectilinear and parallel portions which are disposed between two opposite facing arcuate portions, the two arcuate portions and the two rectilinear portions extending in a same plane, and
wherein the filaments of the rectilinear portions are all directed in a same rectilinear direction.
2. The mechanical component as claimed in claim 1 , comprising at least two inserts positioned on each side of a mid-plane of the mechanical component.
3. The mechanical component as claimed in claim 2 , wherein the two inserts are positioned in planes that are at an angle to one another.
4. The mechanical component as claimed in claim 1 , wherein the mechanical component is a rod presenting an elongate shape in which a length of the rectilinear portions in the rectilinear direction is greater than a distance between the rectilinear portions in a direction perpendicular to the rectilinear direction.
5. An undercarriage comprising at least one mechanical component as claimed in claim 1 .
6. A turbomachine comprising at least one mechanical component as claimed in claim 1 .
7. An aircraft comprising:
a mechanical component as claimed in claim 1 ;
an undercarriage or a turbomachine.
8. The mechanical component as claimed in claim 1 , wherein the two arcuate portions are circular.
