Proposed process suggests robotic placement processing improvements realized by altering cross-sectional shape of wide and flat ribbon materials. Angled cross-section helps composite ribbons to align themselves and correct adjacent tow gaps and overlaps. New prepreg architectures include isosceles triangles, parallelograms, hexagons, and variations of trapezoids.
