Abstract
An illustrative embodiment of the present disclosure provides a method. A composite charge is placed over a forming and cure mandrel, a first radius filler, and a second radius filler. Mechanical pressure is applied to shape the composite charge to the forming and cure mandrel and a rigid base to form a stringer layup having a hat-shaped cross-section. Vacuum pressure is applied to the stringer layup to form a compacted stringer package.
