摘要：
The invention relates to a process for manufacturing a tubular part, which includes an insert made of a metal matrix composite and within which ceramic fibers extend. The process comprises the following steps: the filaments of a filament bundle are fixed close to one end of a support part, said filaments being separate from one another and each filament comprising a ceramic fiber coated with a metal sheath; and all the filaments of the bundle are wound around the support part along a helical path.
