Process for preparing a circular fiberreinforced metallic workpiece

摘要

Process making it possible to produce by isothermal forging circular articles reinforced with fibres over chosen portions of their section, the other portions remaining available for performing the other functions of the article. The invention is noteworthy in that it consists chiefly in producing grooves (8) in a blank (3) of the article (1), in producing preforms (12) from reinforcing fibre and from added metal to the dimensions of the grooves (8), in closing these grooves (8) using plugs (14) and in forming the article (1) by isothermal forging. Application to high-performance rotors such as the rotors of turbine engines employed in aeronautics.
