Aspects of the present disclosure include various exemplary methods relating to composite lamination using one or more arrays of parallel material dispensing heads. In one example, a method of fabricating a high aspect ratio composite article is disclosed which may involve applying a first strip material to a work surface datum at a first angle with a first material dispenser, and applying a plurality of second strip materials to a work surface datum each at a second angle with a plurality of rotatable parallel material dispensers. The method may also involve advancing the first material dispenser and the rotatable parallel material dispensers as a unit the width of the second strip material and continuing application of the first strip material by the first material dispenser and a plurality of second strip materials by the rotatable parallel material dispensers until a desired length is reached.

1. A method of fabricating a high aspect ratio composite article, the method comprising: applying a first strip material to a work surface datum at a first angle with a first material dispenser;applying a plurality of second strip materials to a work surface datum each at a second angle with a plurality of rotatable parallel material dispensers; andadvancing the first material dispenser and the rotatable parallel material dispensers as a unit the width of the second strip material; andcontinuing application of the first strip material by the first material dispenser and a plurality of second strip materials by the rotatable parallel material dispensers until a predetermined length is reached. 2. The method of claim 1, wherein the plurality of second strip materials is applied after the first strip material such that the plurality of second strip materials is applied onto of the first strip material forming the work surface datum for the plurality of second strip materials. 3. The method of claim 1, further comprising positioning a predetermined length of each of the second strip materials for placement, and then applying the predetermined length of each of the second strip materials without moving the rotatable parallel material dispensers as a whole. 4. The method of claim 3, wherein applying the predetermined length of each of the second strip materials includes moving a subcarriage along a track within each rotatable parallel material dispenser. 5. The method of claim 1, further comprising selectively cutting the second strip materials, without cutting backing material, at a selected one of a plurality of different angles as the second strip materials are moving. 6. The method of claim 1, further comprising: reversing direction of the material dispensers so the material dispensers travel in an opposite direction; andapplying a third strip material to a work surface datum at the first angle with a third material dispenser that is in-line with the first material dispenser, but on an opposite side of the rotatable parallel material dispensers. 7. The method of claim 6, further comprising: rotating the plurality of rotatable parallel material dispensers to a third angle;applying a plurality of fourth strip materials each at the third angle with the rotatable parallel material dispensers; andadvancing the first and third material dispensers and the rotatable parallel material dispensers as a unit the width of the fourth strip material; andcontinuing application of the third strip material by the third material dispenser and a plurality of fourth strip materials by the rotatable parallel material dispensers until a desired length is reached. 8. The method of claim 7, wherein the third angle is substantially perpendicular to the first angle. 9. The method of claim 7, further comprising: once again reversing the direction of the material dispensers so the material dispensers travel in the opposite direction;applying the first strip material onto the plurality of fourth strip materials at the first angle with the first material dispenser;rotating the plurality of rotatable parallel material dispensers to a fourth angle;applying a plurality of fourth strip materials each at the fourth angle with the rotatable parallel material dispensers; andadvancing the first and third material dispensers and the rotatable parallel material dispensers as a unit the width of the fourth strip material and continuing application of the first strip material by the first material dispenser and a plurality of fourth strip materials by the rotatable parallel material dispensers until a desired length is reached. 10. The method of claim 9, wherein a multiple ply layup is formed with layers of material at the first angle, the second angle, the third angle and the fourth angle. 11. The method of claim 9, wherein the first angle is substantially parallel to the direction of travel of the material dispensers, the second angle is about positive forty-five degrees relative to the first angle, the third angle is about ninety degrees relative to the first angle, and the fourth angle is about negative forty-five degrees relative to the first angle such that a multiple ply layup is formed having a first zero degree layer, a forty-five degree layer on top of the first zero degree layer, a second zero degree layer on top of the forty-five degree layer, a ninety degree layer on top of the second zero degree layer, a third zero degree layer on top of the ninety degree layer, and a negative forty-five layer on top of the third zero degree layer. 12. The method of claim 1, wherein the first strip material is dispensed from a first supply of strip material onboard the first material dispenser, and wherein each of the second strip materials is dispensed from a second supply of strip material onboard a corresponding one of the rotatable parallel material dispensers. 13. A method of fabricating a high aspect ratio composite article, the method comprising: applying a first strip material to a work surface datum at a first angle with a first material dispenser, wherein the first strip material is dispensed from a first supply of strip material onboard the first material dispenser;applying a plurality of second strip materials after the first strip material to a work surface datum each at a second angle with a plurality of rotatable parallel material dispensers, wherein each of the second strip materials is dispensed from a second supply of strip material onboard a corresponding one of the rotatable parallel material dispensers; andadvancing the first material dispenser and the rotatable parallel material dispensers as a unit the width of the second strip material; andcontinuing application of the first strip material by the first material dispenser and a plurality of second strip materials by the rotatable parallel material dispensers until a predetermined length is reached. 14. The method of claim 13, wherein the plurality of second strip materials are applied onto of the first strip material forming the work surface datum for the plurality of second strip materials. 15. The method of claim 13, further comprising positioning a predetermined length of each of the second strip materials for placement, and then applying the predetermined length of each of the second strip materials without moving the rotatable parallel material dispensers as a whole. 16. The method of claim 15, wherein applying the predetermined length of each of the second strip materials includes moving a subcarriage along a track within each rotatable parallel material dispenser. 17. The method of claim 13, further comprising selectively cutting the second strip materials, without cutting backing material, at a selected one of a plurality of different angles as the second strip materials are moving. 18. The method of claim 13, further comprising: reversing direction of the material dispensers so the material dispensers travel in an opposite direction; andapplying a third strip material to a work surface datum at the first angle with a third material dispenser that is in-line with the first material dispenser, but on an opposite side of the rotatable parallel material dispensers. 19. The method of claim 18, further comprising: rotating the plurality of rotatable parallel material dispensers to a third angle;applying a plurality of fourth strip materials each at the third angle with the rotatable parallel material dispensers; andadvancing the first and third material dispensers and the rotatable parallel material dispensers as a unit the width of the fourth strip material and continuing application of the third strip material by the third material dispenser and a plurality of fourth strip materials by the rotatable parallel material dispensers until a predetermined length is reached. 20. The method of claim 19, wherein the third angle is substantially perpendicular to the first angle.
