Abstract (en)

[origin: EP0775754A1] A method is claimed for the fabrication of a rotor in a composite material with a metal matrix (1, 2, 3, 26), made up of a metal block containing fibres arranged in circles. The method comprises: (a) constructing a metal medium (1) made up of a plate and a shaft; (b) placing a metal disc (3) on the shaft with a metal ring (2) that extends around the disc (3); (c) winding the fibres, coated with the matrix material, around the shaft and between the disc (3) and the plate; (d) arranging a metal casing (26) around the plate and the fibres, the ring (2) passing beyond the casing (26) and the shaft and freeing the ring (2) from the disc (3); (e) surrounding the medium (1), the casing (26) and the ring (2) with a sleeve (27) fitted with a degassing aperture (28); (f) compressing the sleeve (27) by hot isostatic compression until the ring (2) embeds itself and attains a determined level; and (g) removing the sleeve (27) and machining the metal block to a desired shape should this be necessary.
