ABSTRACT:
Methods for forming a composite ring having unidirectional filaments embedded in a polymer matrix is disclosed. The filaments are spirally wound within the ring to form a plurality of essentially circular hoops which are in coaxial alignment with the expected lines of principle force. In one embodiment the formed ring is structurally integrated into the rotor of a gas turbine engine to reinforce the rotor and to restrain the rotor blades which extend outwardly of the ring.
