Abstract
A contoured composite structure includes an axis of curvature and at least one curved leg. The structure is fabricated by laying up a flat stack of prepreg fiber plies each having non-zero degree fiber orientations relative to an axis of curvature, and laying up at least one prepreg fiber ply on the stack having a zero degree fiber orientation. Laying up the zero degree ply includes placing prepreg tows in segments arranged end-to-end on at least a portion of the stack. The stack is formed into a web and a curved leg.
