ABSTRACT:
A device is disclosed for forwarding a medium in the form of a gas, liquid, or loose particles. The medium can contain additives and/or contaminants in an aggregate state other than that of the medium itself. The device's major components are form-fit and force-fit together and comprise at least one supporting component along with blade-like components fastened to it. The supporting component is, or the supporting components are, made of a fiber-filled composite. The device is in particular an impeller for a pump, turbine, or similar mechanism. It is characterized in that the supporting component is, or the supporting components are, made of a lattice of essentially continuous fibers of carbon and/or ceramic and of a matrix that contains carbon and in that the fibers are sheathed with silicon carbide resulting from the infiltration of liquid silicon and from its reaction essentially with the carbon in the matrix.
