Abstract

Systems for constructing complex composite structures include a conveyor and two or more stations operatively and sequentially positioned relative to the conveyor. Each station is configured to operatively deposit a layer of composite material on the conveyor. Methods of constructing a complex composite structure include laying up a first layer of composite material having a first configuration and laying up a second layer of composite material having a second configuration at least partially over the first layer.

First claim

The invention claimed is:

1. A system for constructing complex composite structures, the system comprising:
a primary conveyor; and
two or more stations operatively and sequentially positioned relative to the conveyor, wherein each station is configured to operatively deposit a layer of fiber reinforced composite material on the primary conveyor to construct a complex composite structure, wherein the two or more stations include at least a first station that includes:
a first localized roller operatively oriented at an angle relative to a longitudinal axis of the primary conveyor, wherein the angle is 0-90 or 90-180 degrees relative to the longitudinal axis of the primary conveyor, and wherein the first localized roller is configured to translate along its longitudinal axis to and from a position that is operatively above the primary conveyor; and
a first layer depositing machine configured to deposit a layer of fiber reinforced composite material across the first localized roller as the first localized roller translates to the position that is operatively above the primary conveyor;
wherein the first localized roller is configured to rotate in a first direction as it translates to the position that is operatively above the primary conveyor, and to operatively transfer a layer of fiber reinforced composite material from the first localized roller to the primary conveyor as the first localized roller rotates in a second direction opposite the first direction and translates away from the position that is operatively above the primary conveyor.

2. The system of claim 1 , wherein a downstream station of the two or more stations is configured to operatively deposit a layer of fiber reinforced composite material at least partially over a layer of fiber reinforced composite material operatively deposited on the primary conveyor by an upstream station of the two or more stations.

3. The system of claim 1 , wherein the two or more stations include at least a second station that includes:
a second layer depositing machine configured to deposit a layer of fiber reinforced composite material longitudinally along the primary conveyor as the primary conveyor translates relative to the layer depositing machine.

4. The system of claim 3 , wherein the second layer depositing machine is configured to deposit a layer of fiber reinforced composite material along the primary conveyor with fibers of the fiber reinforced composite material longitudinally aligned with the primary conveyor.

5. The system of claim 1 , wherein the two or more stations include at least a second station that includes:
a second layer depositing machine configured to deposit a layer of fiber reinforced composite material laterally across the primary conveyor.

6. The system of claim 5 , wherein the second layer depositing machine is configured to deposit a layer of fiber reinforced composite material laterally across the primary conveyor with fibers of the fiber reinforced composite material extending laterally across the primary conveyor.

7. The system of claim 1 , wherein the two or more stations include at least a second station that includes:
a localized conveyor operatively positioned above the primary conveyor and longitudinally aligned with the primary conveyor; and
a second layer depositing machine configured to deposit a layer of fiber reinforced composite material laterally across the localized conveyor;
wherein the localized conveyor is configured to operatively transfer a layer of fiber reinforced composite material from the localized conveyor to the primary conveyor.

8. The system of claim 7 , wherein the second layer depositing machine is configured to deposit a layer of fiber reinforced composite material laterally across the localized conveyor with fibers of the fiber reinforced composite material extending laterally across the primary conveyor.

9. The system of claim 1 , wherein the two or more stations include at least a second station that includes:
a second layer depositing machine configured to deposit a layer of fiber reinforced composite material across the primary conveyor at an angle relative to a longitudinal axis of the primary conveyor, wherein the angle is 0-90 or 90-180 degrees relative to the longitudinal axis of the primary conveyor.

10. The system of claim 9 , wherein the second layer depositing machine is configured to deposit a layer of fiber reinforced composite material across the primary conveyor with fibers of the fiber reinforced composite material extending across the primary conveyor at the angle.

11. The system of claim 1 , wherein the two or more stations include at least a second station that includes:
a second localized roller operatively positioned above the primary conveyor at an angle relative to a longitudinal axis of the primary conveyor, wherein the angle is 0-90 or 90-180 degrees relative to the longitudinal axis of the primary conveyor; and
a second layer depositing machine configured to deposit a layer of fiber reinforced composite material across the second localized roller;
wherein the second localized roller is configured to operatively transfer a layer of fiber reinforced composite material from the localized roller to the primary conveyor.

12. The system of claim 11 , wherein the second layer depositing machine is configured to deposit a layer of fiber reinforced composite across the second localized roller with fibers of the fiber reinforced composite material extending laterally around the second localized roller.

13. The system of claim 1 , wherein the two or more stations include at least a second station that includes:
a localized conveyor operatively positioned above the primary conveyor and longitudinally aligned with the primary conveyor; and
a second layer depositing machine configured to deposit a layer of fiber reinforced composite material across the localized conveyor at an angle relative to a longitudinal axis of the primary conveyor, wherein the angle is 0-90 or 90-180 degrees relative to the longitudinal axis of the primary conveyor;
wherein the localized conveyor is configured to operatively transfer a layer of fiber reinforced composite material from the localized conveyor to the primary conveyor.

14. The system of claim 13 , wherein the second layer depositing machine is configured to deposit a layer of fiber reinforced composite material across the localized conveyor with fibers of the fiber reinforced composite material extending across the primary conveyor at the angle.

15. The system of claim 1 , wherein the first layer depositing machine is configured to deposit a layer of fiber reinforced composite material across the first localized roller with fibers of the fiber reinforced composite material longitudinally aligned with the first localized roller.

16. The system of claim 1 , wherein the fiber reinforced composite material includes pre-preg composite material.

17. The system of claim 1 , wherein the complex composite structure includes at least a portion of an aircraft fuselage, a wing section of an aircraft, a wing of an aircraft, a stabilizer section of an aircraft, a stabilizer of an aircraft, a structural section of an aircraft, and/or an aircraft.

18. A method of constructing a complex composite structure utilizing the system of claim 1 , the method comprising:
laying up a first layer of fiber reinforced composite material having a first configuration; and
laying up a second layer of fiber reinforced composite material having a second configuration at least partially over the first layer to at least
