Abstract
Prepreg tows are placed on a substrate having a bend with a curvature extending over a transition region in the substrate. The tows are steered and laid on the substrate in at least a first section and a second section within the transition region, wherein each of the first and second sections has an angular orientation that is less than the curvature of the bend in order to reduce gathering of the tows.
