摘要： A process for manufacturing a metal part reinforced with ceramic fibers including machining at least one housing for an insert in a metal body having an upper face. At least one insert formed from ceramic fibers in a metal matrix is placed in the housing. The insert is covered with a cover. A vacuum is created in the interstitial space around the insert and the interstitial space is hermetically sealed under vacuum. The assembly, namely the metal body with the cover, is treated by hot isostatic pressure. The treated assembly is machined in order to obtain the part. The cover includes an element covering the insert in the slot and projecting from the upper face, and a sheet covering the upper face with said element. In particular, the insert is straight and the housing for the insert in the metal body forms a straight slot.

摘要： The invention relates to a method of fabricating a mechanical member, the method including a plurality of operations of braiding and depositing layers of braided reinforcing fibers on a mandrel (11) by using braiding machine. Each operation comprises braiding a braided layer and depositing it by moving the mandrel (11) along a central axis of the braiding machine. Each of the various superposed braided layers comprises both longitudinal fibers (12, 12G) that are parallel to a main direction of the mandrel (11), and interlacing fibers that are inclined. At least one operation is configured to form and deposit a braided layer having, in at least one cross-section of the member, a density of longitudinal fibers that differs depending on whether consideration is given to one angular region (S1) or another angular region (S2) of the same extent around the center of gravity (G) of the mandrel (11) in the section under consideration. The invention applies to fabricating structural elements in the field of aviation.

摘要： The invention relates to a process for manufacturing a connecting rod (19) made of a composite having one end in the form of a clevis (21). According to the invention, a layer (16a-16e) of reinforcing fibres (14) braided around a mandrel (5) is applied by a braiding machine (12) over the entire length of the mandrel (5); a layer (17a-17d) of reinforcing fibres is then applied by a winding machine around the end (7) (5) corresponding to the clevis (21); other layers of braided fibres (16a-16e) and wound fibres (17a-17d) are applied alternately until constituting a fibre (14) thickness sufficient for the clevis (21) to be formed. Resin is then injected into the various layers (16a-16e, 17a-17d) of braided and wound fibres, the resin then being cured, and the end comprising the wound layers (17a-17d) is machined in order to form thereat the clevis (21).
