Abstract
A curved composite element is laid up over a tool having first and second curved tool surfaces possessing differing radii of curvatures. A plurality of composite fiber ply segments are arranged in substantially side-by-side relationship into a group. The ply segments are formed as a group onto the first curved tool surface, and the group is then formed from the first curved tool surface onto the second curved tool surface.
