An apparatus (100) for fabricating composite structures is provided that includes first and second tooling portions (110, 120) that are configured to support at least one layer (160) of composite materials during curing to form a composite structure. The apparatus (100) further includes a flexible hinge (140) that is disposed between and couples the first and second tooling portions (110, 120). The flexible hinge (140) couples the tooling portions (110, 120) such that they may be peeled away from the composite material after curing by bending the apparatus (100) at the flexible hinge (140).

1. An apparatus for fabricating composite structures, comprising: first and second tooling portions configured to support at least one layer of uncured composite material during a curing process to form a composite structure; a flexible hinge disposed between and coupling the first and second tooling portions such that the first and second tooling portions may be peeled away from the composite material after curing by bending the apparatus at the flexible hinge; and a pressure insert coupled to an inner surface of the first and second tooling portions. 2. The apparatus of claim 1, wherein the flexible hinge comprises elastomeric material. 3. The apparatus of claim 1, wherein the first and second tooling portions comprise a metallic material. 4. The apparatus of claim 1, wherein the first and second tooling portions each comprise a fiber-reinforced plastic laminate. 5. The apparatus of claim 4, wherein the flexible hinge is joined with the first and second tooling portions by co-curing the flexible hinge with the laminate of the first and second portions. 6. The apparatus of claim 4, wherein the flexible hinge is bonded with the first and second tooling portions after the first and second tooling portions are cured. 7. The apparatus of claim 4, wherein the flexible hinge comprises tabs interleaved with layers of the laminate of the first and second tooling portions. 8. The apparatus of claim 1, further comprising a layer of rubber disposed over a molding surface of the first and second tooling portions and over the flexible hinge. 9. The apparatus of claim 1, wherein the first and second portions are disposed normally to one another such that the tooling portions may support layers of composite materials to form one half of a blade. 10. The apparatus of claim 1, wherein the first tooling portion is configured to conform with a crossing member disposed on a skin. 11. The apparatus of claim 10, wherein the crossing member is a hat beam. 12. An apparatus for fabricating composite structures, comprising: first, second, and third tooling portions configured to support at least one layer of uncured composite material during a curing process to form a composite structure, the first tooling portion positioned generally parallel to the third tooling portion, and the second tooling portion disposed between and generally normal to the first and third tooling portions; a first flexible hinge disposed between and coupling the first and second tooling portions; and a second flexible hinge disposed between and coupling the second and third tooling portions.
