摘要:
A process for manufacturing a component with an insert made of a composite is disclosed. The composite includes a metal matrix, within which ceramic fibers extend. The insert is made of a composite which is obtained from a plurality of coated filaments, each filament includes a ceramic fiber coated with a metal sheath. The process includes winding a bundle or bonded sheet of coated filaments around a body of revolution perpendicular to the axis of rotation of said body. The insert is then subjected to a hot isostatic pressing step in a container. The process is applied to the manufacture of aeronautical turbomachine components.
摘要:
A method for creating a metal reinforcement for a leading or trailing edge of a turbine engine blade including a reinforcement foot and head, the method including: creating a plurality of V-shaped tapered elements that form different parts of the metal reinforcement so that the metal reinforcement is divided into a plurality of parts distributed between the foot and the head; positioning the parts on equipment that is shaped like the leading or trailing edge of the turbine engine blade; and rigidly connecting the different parts so as to form the complete profile of the one-piece metal reinforcement the by recombining the different parts.
摘要:
The invention relates to a method of producing a guide vane, the method comprising a step of fabricating at least a portion of a metal body of the guide vane by additive fabrication, with at least one outside surface thereof presenting a plurality of cavities; and a step of filling said cavities with a material of lower density than the metal body in order to form at least one substantially smooth airfoil surface.
摘要:
An assembly including a stack structure made up of the following elements assembled together by brazing: the titanium-based metal piece; a first intermediate piece suitable for deforming to accommodate differential expansion between the metal piece and a piece made of ceramic material based on silicon carbide and/or carbon; a second intermediate piece that is rigid, having a coefficient of expansion close to that of said ceramic material piece and made of aluminum nitride (AlN) or of tungsten (W); and the ceramic material piece is disclosed.
摘要:
An assembly including a metal piece, a piece made of ceramic material, and at least one intermediate connection element assembled to each of the pieces by brazing. The intermediate connection element includes a deformable sheet presenting at least two flat zones brazed to respective ones of the pieces, the two flat zones being interconnected by a deformable zone presenting at least two free undulations oriented in alternation towards the metal piece and towards the piece made of ceramic material.
