A composite material is formed of several assembled discs of matrix material, wherein each disc preferably has at least one groove therein, and at least one fiber () is inserted in each groove. A composite of matrix material and fibers () is present in an inner section (), whereas exclusively the matrix material is present in an outer section (). The inner section with the fibers () reaches to different radial extents toward the outer section (), to achieve a strength-optimizing intermeshing of the inner section () with the outer section ().

Composite material, method for the production of a composite material and the utilization thereof

A compressor in a multi-stage axial form of construction, with a rotor which is mounted overhung and includes a plurality of moving-blade rings on blade carriers connected to one another, and with a blade arrangement, in which the moving-blade ring of the first stage forms the blade cascade arranged furthest upstream. At least one of the rotating blade carriers is produced in an MMC form of construction, that is to say as a metal component fiber-reinforced at least in regions, and the rotary bearing absorbing the large part of the radial loads occurring on the rotor has a predetermined breaking point which, when a defined radial load is exceeded, allows a radial shift of the rotor, with the result that the latter brushes against the stator.
