Tooling aids for applying pressure in laminating, and methods for their use, are described herein. In one embodiment, a caul for applying pressure in laminating includes a base portion positioned between first and second corner portions. The base portion can have a curved shape when it is in a relaxed state, but it moves to a flatter shape when subjected to pressure during lamination. Movement of the base portion to the flatter shape causes the first and second corner portions to move outwardly and away from the base portion. In this manner, the caul can be used to compact laminating materials into corner regions of a corresponding female mold surface.

I claim: 1. A tooling aid for applying pressure to a laminate on a mold surface, the tooling aid comprising: a base portion having a curved surface portion configured to be positioned proximate to a side region of the mold surface; and a corner portion configured to be positioned proximate to a transition region of the mold surface, wherein flexing the base portion toward the side region of the mold surface flattens the curved surface portion against the side region and drives the corner portion away from the base portion and toward the transition region of the mold surface. 2. The tooling aid of claim 1 wherein the base portion and the corner portion are two portions of a single piece of sheet metal. 3. The tooling aid of claim 1 wherein the base portion and the corner portion are two portions of a single piece of plastic. 4. The tooling aid of claim 1 wherein the base portion and the corner portion are two portions of a single piece of vacuum-molded thermoplastic. 5. The tooling aid of claim 1 wherein the base portion and the corner portion are two portions of a single piece of roto-molded thermoplastic. 6. The tooling aid of claim 1 wherein the base portion includes an exterior surface portion having an uneven texture. 7. The tooling aid of claim 1 wherein the base portion includes an exterior surface portion having a plurality of grooves. 8. The tooling aid of claim 1 wherein the base portion includes an exterior surface portion having a plurality of ridges. 9. The tooling aid of claim 1 wherein the corner portion is a first corner portion configured to be positioned proximate to a first transition region of the mold surface, and wherein the tooling aid further comprises a second corner portion configured to be positioned proximate to a second transition region of the mold surface, wherein flexing the base portion toward the side region of the mold surface drives the first corner portion toward the first transition region and the second corner portion toward the second transition region. 10. A system for laminating a plurality of plies together, the system comprising: a tool having a mold surface configured to support the plies, the mold surface having a side region proximate to a transition region; and a tooling aid for applying pressure to the plies on the mold surface, the tooling aid comprising: a base portion configured to be positioned proximate to the side region of the mold surface, wherein the base portion includes a cambered surface portion configured to face the side region of the mold surface; and a corner portion configured to be positioned proximate to the transition region of the mold surface, wherein flexing the base portion toward the side region of the mold surface drives the corner portion away from the base portion and toward the transition region of the mold surface, and wherein flexing the base portion toward the side region of the mold surface flattens the cambered surface portion against the side region. 11. The system of claim 10 wherein the tool is a female tool. 12. The system of claim 10 wherein the transition region of the mold surface is a first transition region, and wherein the mold surface further comprises a second transition region spaced apart from the first transition region, the side region of the mold surface being positioned between the first and second transition regions. 13. The system of claim 10, further comprising a sealing layer configured to be positioned over the tooling aid and at least partially evacuated. 14. The system of claim 10, further comprising a sealing layer configured to be positioned over the tooling aid and at least partially evacuated, wherein evacuating the sealing layer causes the base portion of the tooling aid to flex toward the side region of the tool surface. 15. The system of claim 10 wherein the mold surface of the tool is configured to support a plurality of fiber plies, and wherein the system further comprises a resin infusion system operably coupled to the mold surface and configured to infuse the fiber plies with resin. 16. The system of claim 10 wherein the mold surface of the tool is configured to support a plurality of fiber plies, and wherein the system further comprises: a sealing layer configured to be positioned over the tooling aid and at least partially evacuated, wherein evacuating the sealing layer causes the base portion of the tooling aid to flex toward the side region of the tool surface; and a resin infusion system operably coupled to the mold surface, wherein the resin infusion system is configured to infuse the fiber plies with resin after the sealing layer has been evacuated. 17. A system for laminating a plurality of fiber plies together, the system comprising: mold means for supporting the fiber plies in a shape of a part; first means for compacting a first portion of the fiber plies against a flat portion of the mold means, wherein the first means include a curved surface portion configured to face the flat portion of the mold means; and second means for compacting a second portion of the fiber plies against a curved portion of the mold means in response to the curved surface portion of the first means flattening against the flat portion of the mold means and compacting the first portion of fiber plies against the flat portion of the mold means. 18. The system of claim 17, further comprising evacuating means for exerting air pressure against the fiber plies on the mold means, wherein the first means is responsive to the evacuating means. 19. The system of claim 17 wherein the mold means include means for forming an outside mold line of a laminated part. 20. The system of claim 17, further comprising means for infusing the fiber plies with resin. 21. The system of claim 17 wherein the mold means include means for supporting the fiber plies in the shape of an aircraft part. 22. A tooling aid for applying pressure to material on a mold surface, the tooling aid comprising: a base portion movable between a first position in which it has a generally bowed shape and a second position in which it has a generally flat shape; and a corner portion attached to the base portion, wherein the corner portion is movable with the base portion between a third position when the base portion is in the first position and a fourth position when the base portion is in the second position, the fourth position being located outwardly from the third position. 23. The tooling aid of claim 22 wherein the base portion and the corner portion are two portions of an integral piece of material. 24. A tooling aid for applying pressure to a laminate on a mold surface, the tooling aid comprising: a base portion configured to be positioned proximate to a side region of the mold surface, wherein the base portion includes a cambered surface portion configured to face the side region of the mold surface; and a corner portion configured to be positioned proximate to a transition region of the mold surface, wherein flexing the base portion toward the side region of the mold surface drives the corner portion away from the base portion and toward the transition region of the mold surface, and wherein flexing the base portion toward the side region of the mold surface flattens the cambered surface portion against the side region. 25. A tooling aid for applying pressure to a laminate on a mold surface, the tooling aid comprising: a base portion configured to be positioned proximate to a side region of the mold surface; and a corner portion configured to be positioned proximate to a transition region of the mold surface, wherein the base portion includes a first surface portion curved in a first direction, and the corner portion includes a second surface portion curved in a second direction, opposite to the first direction, and wherein flexing the base portion toward the side region of the mold surface drives the corner portion away from the base portion and toward the transition region of the mold surface.
