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.
