Abstract
A process for manufacturing a coiled insert of coated filaments is disclosed. Each filament includes a ceramic fiber coated with a metal sheath. The process includes a step of winding a sheet of coated filaments around a piece. At the start of winding, a first metal shim is placed beneath the sheet and coiled. At the end of winding, a second metal shim is placed on the sheet and coiled. The process is applied to the manufacture of aeronautical turbomachine components.
Claims10
A process for manufacturing a coiled insert of coated filaments, each filament comprising a ceramic fiber coated with a metal sheath, the process comprising:
- manufacturing a sheet of coated filaments by laser welding;
- and
- winding a sheet of coated filaments around a piece,
- wherein at the start of winding, a first metal shim is placed beneath the sheet and coiled such that the first metal shim provides an internal part of the coiled insert,
- wherein at the end of winding, a second metal shim is placed on the sheet and coiled such that the second metal shim provides an external part of the coiled insert,
- wherein a portion of an innermost layer of the coiled insert is sandwiched between a first end portion of the first metal shim and a second end portion of the first metal shim, and
- wherein a portion of an outermost layer of the coiled insert is sandwiched between a first end portion of the second metal shim and a second end portion of the second metal shim.
