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.
