A composite turbine disc includes a bore section providing a first set of mechanical and temperature resistance properties, and a rim section which provides a second set of mechanical and temperature resistance properties. The second set of mechanical properties and temperature resistance are superior to the first set of properties. An intermediate diaphragm section is disposed between the bore section and the rim section. The intermediate section has mechanical and temperature resistance properties in a range between the first and second set of properties.
