Abstract:
1. A method of manufacturing a mechanical component including 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 having a longitudinal axis, each coated filament including a ceramic fiber coated with a metal sheath, the method comprising: manufacturing an insert preform by winding a bonded lap or bundle of coated filaments about a cylindrical component, wherein the insert perform includes a portion which extends in a rectilinear direction parallel to the longitudinal axis of the coated filaments and a portion which is curved; inserting the insert preform in a first container; performing hot isostatic compaction of the first container; and machining the first container to remove the curved portion of the insert preform and a corresponding portion of the first container so as to form a rectilinear insert extending rectilinearly between a first end and a second end, wherein the coated filaments corresponding to the portion of the insert preform extending in the rectilinear direction are provided in the rectilinear insert such that all of the coated filaments in the rectilinear insert extend in the rectilinear direction.
