PROCEDE ET DISPOSITIF POUR FABRIQUER UN ELEMENT COMPOSITE SYMETRIQUE ENROTATION

摘要

A rotationally symmetrical compound body make by centrifugal casting in which the metal to be cast is poured with the aid of a rotating or stationary casting device disposed axially in a rotating drum either radially or tangentially onto the endless fibers, stable fibers or fiber matting abutting at the inner wall of the drum, whereby the outer fiber-reinforced layers of the compound body adjoining the wall of the drum are heated and cool off to room temperature only after the cooling off of the inner metallic layers; the thermal coefficient of expansion of the inner metallic layers is equal to or smaller than that of the outer layers.
