Abstract
A method for forming a composite stiffener includes locating a composite sheet on a support surface such that a first sheet-portion of the composite sheet is supported on the support surface and a second sheet-portion of the composite sheet extends beyond the support surface. The method includes separating the second sheet-portion from the first sheet-portion to at least partially form a composite charge. The method includes transferring the composite charge onto a layup surface of a layup tool, wherein the layup surface comprises a curvature along a longitudinal tool-axis of the layup tool. The method includes selectively positioning the layup tool relative to a compaction device such that a compaction force, applied to the composite charge by the compaction device, is normal to the layup surface. The method includes compacting the composite charge on the layup surface to form a portion of the composite stiffener.
