Abstract
A method includes dispensing a first set of lanes, that each comprise a tow of fiber-reinforced material, at a first angle such that the lanes are placed side-by-side with respect to each other, forming a first layer of a multi-lane tow. The method further includes applying a film directly in contact with multi-lane tow that resists shear forces applied to the multi-lane tow, transporting the multi-lane tow to a mandrel, and compacting the multi-lane tow via a Ply-By-Ply (PBP) machine disposed at the mandrel. The method further comprises removing the film from the multi-lane tow.
