A method of manufacturing a composite turbine rotor in which blade coupons are fabricated from flat braided fabrics that have extending axial fibers. The extending axial fibers are then woven between the plies of polar woven fabric which make up the body of the rotor. This preform assembly is then impregnated with resin and cured. The blade coupons make up the blades of the rotor and can be made to have an airfoil shape, a curved shape, or a twisted shape by the use of blade formation tools designed for forming the rotor preform.

Composite turbine rotor

A braiding machine carrier having a frame; a fiber spool mount attached to the frame; a fiber take-up assembly including a spiral spring; gear train on the frame for mechanically connecting the take-up spring assembly to the fiber spool mount for winding the spiral spring as a spool on the mount rotates; and a magnetic clutch, coupled to the take-up spring assembly, for preventing overwinding of the spiral spring.
