Abstract
A system for manufacturing a stiffened composite panel may include a stiffener tooling assembly, a caul plate, and a rotatable strongback. The stiffener tooling assembly may include stiffener tooling configured to support a plurality of composite stiffeners. The caul plate may have a layup surface for laying up a composite skin. The strongback may be releasably coupled to the caul plate. The system may include a plurality of hinges each having a fixed hinge portion and a movable hinge portion. The movable hinge portion may be coupled to the strongback for rotation thereof between an open position and a closed position for engagement of the caul plate with the stiffener tooling assembly.
