A turbomachinery disk is provided that has a rim portion, an intermediate portion, and a hub portion. Annular flanges extend axially on both direction from the hub portion. Disposed concentrically about these flanges is a ring of reinforced composite fibers. The ring of composite fibers is of sufficient mass that some of the hoop stress in the hub portion will be transferred to the ring. As a result the mass of the disk is less than the mass of a conventional disk without the composite ring.

A rotatable turbomachinery disk comprising:a rim portion,an intermediate portion,a hub portion having at least one axial extending annular flange,a ring of reinforced composite fibers concentric about said flange andan annular dam extending radially outward from said flange and axial spaced from said hub portion to define an annular surface for receiving an annular spool. [10.]10. A rotatable turbomachinery disk comprising:a rim portion,an intermediate portion,a hub portion having at least one axial extending annular flange,a ring of reinforced composite fibers concentric about said flange andan annular spool mounted to said flange and having two radially extending lips axially spaced apart to define a surface for receiving said composite fiber ring.11. The disk of claim 6 further comprising a cover plate mounted to said disk and to an adjoining shaft, said cover plate shaped to cover said flange, said annular spool and said composite ring. [12.]12. A rotatable turbomachinery disk comprising:a rim portion,an intermediate portion,a hub portion having at least one axial extending annular flange,a ring of reinforced composite fibers concentric about said flange anda shaft adjacent said disk and having an axial extending surface in concentric contact with said flange of said hub portion, said axial extending surface having an annular spool mounted thereto, said spool having two radially extending lips axially spaced apart to define a surface for receiving said composite fiber ring.13. The disk of claim 12 further comprising a cover plate mounted to said disk and to said shaft, said cover plate shaped to cover said annular spool and said composite ring. [14.]14. A rotatable turbomachinery disk comprising:a rim portion,an intermediate portion,a hub portion having at least one axial extending annular flange,a ring of reinforced composite fibers concentric about said flange anda shaft adjacent said disk and having an axial extending surface on concentric contact with said flange, said shaft further having a radial extending flange axially spaced apart from a radially extending dam to define a surface for receiving said composite ring.15. A rotatable turbomachinery disk comprising:a rim portion,an intermediate portion,a hub portion having at least one axial extending annular flange,a ring of reinforced composite fibers concentric about said flange andsaid disk further comprising two parts bolted together to define a hollow interior and said flange has an axial extending surface facing said interior for receiving said composite ring.16. The disk of claim 15 further comprising an annular spool disposed between said composite ring and said axial extending surface.17. A rotatable turbomachinery disk comprising:a rim portion,an intermediate portion,a hub portion having at least one axial extending annular flange,a ring of reinforced composite fibers concentric about said flange and encased in a metal ring.
