Manufacturing Process Using Bladderless Mold Line Conformal Hat Stringer

Techniques for manufacturing structures that include composite hat stringers are disclosed. In one embodiment, a method of forming a composite structure includes placing a generally cured composite hat stringer on a tool, the hat stringer having a rigid mold line conformal surface for adjoining a ge...

Zusammenfassung:	Techniques for manufacturing structures that include composite hat stringers are disclosed. In one embodiment, a method of forming a composite structure includes placing a generally cured composite hat stringer on a tool, the hat stringer having a rigid mold line conformal surface for adjoining a generally uncured skin, positioning the skin adjacent to the rigid mold line conformal surface, coupling the skin to the rigid mold line conformal surface of the composite hat stringer, including applying a pressure to a surface of the skin to urge the skin into engagement with the composite hat stringer, and curing the skin.
