Abstract

A system for fabricating a composite structure includes a ply carrier including a ply support surface configured to support at least one composite ply. The system includes a carrier transfer device configured to convey the ply carrier. The system includes a lamination system configured to selectively apply the at least one composite ply to the ply support surface of the ply carrier. The system includes a transfer system configured to remove the ply carrier from the carrier transfer device and to apply the at least one composite ply to at least a portion of a forming surface of a forming tool. The system includes a forming system configured to form the at least one composite ply over the at least a portion of the forming surface of the forming tool.

First claim

What is claimed is:

1. A system for fabricating a composite structure, the system comprising:
a ply carrier comprising:
a base plate; and
a film positioned on the base plate, wherein the film forms a ply support surface configured to support at least one composite ply;

a carrier transfer device configured to convey the ply carrier;
a lamination system configured to selectively apply the at least one composite ply to the ply support surface of the ply carrier;
a transfer system configured to remove the ply carrier from the carrier transfer device and to apply the at least one composite ply to at least a portion of a forming surface of a forming tool; and
a forming system configured to form the at least one composite ply over the at least a portion of the forming surface of the forming tool.

2. The system of claim 1 , further comprising a trim system configured to selectively cut the at least one composite ply into a predetermined shape.

3. The system of claim 2 , further comprising a scrap removal system configured to remove a remnant of the at least one composite ply from the ply support surface after the at least one composite ply is cut into the predetermined shape.

4. The system of claim 1 , further comprising a carrier preparation system configured to apply the film to the base plate.

5. The system of claim 1 , wherein:
the base plate comprises a plurality of vacuum apertures; and
the carrier transfer device comprises a vacuum table in fluid communication with the plurality of vacuum apertures and configured to apply a retention vacuum to the plurality of vacuum apertures to retain the film on the base plate.

6. The system of claim 1 , further comprises an indexing structure configured to operatively locate the ply carrier at a specified location on the carrier transfer device.

7. The system of claim 1 , further comprising a positioning system configured to selectively position the carrier transfer device relative to the lamination system and the transfer system.

8. The system of claim 7 , further comprising a tool transfer device configured to convey the forming tool,
wherein the positioning system is further configured to selectively position the tool transfer device relative to the transfer system and the forming system.

9. The system of claim 8 , further comprising an indexing device configured to operatively locate the carrier transfer device at a plurality of specified locations relative to each one of the lamination system and the transfer system.

10. The system of claim 9 , wherein the indexing device is further configured to operatively locate the tool transfer device at a plurality of specified locations relative to each one of the transfer system and the forming system.

11. The system of claim 1 , further comprising a controller programmed to control operation of at least one of: the carrier transfer device, the lamination system and the transfer system and the forming system.

12. A system for fabricating a composite structure, the system comprising:
a ply carrier comprising:
a base plate; and
a film positioned on the base plate, wherein the film forms a ply support surface;

a carrier transfer device configured to support and convey the ply carrier;
a lamination system configured to apply at least one composite ply to the ply support surface of the ply carrier;
a transfer system in sequential relation to the lamination system and configured to remove the ply carrier from the carrier transfer device and to apply the at least one composite ply to at least a portion of a forming surface of a forming tool;
a forming system in sequential relation to the transfer system and configured to form the at least one composite ply over the at least a portion of the forming surface of the forming tool; and
a controller programmed to control operation of the carrier transfer device, the lamination system, the transfer system, and the forming system.

13. The system of claim 12 , further comprising a trim system in sequential relation between the lamination system and the transfer system and configured to selectively cut the at least one composite ply into a predetermined shape,
wherein the controller is further programmed to control operation of the trim system.

14. The system of claim 13 , further comprising a scrap removal system configured to remove a remnant of the at least one composite ply from the ply support surface after the at least one composite ply is cut into the predetermined shape,
wherein the controller is further programmed to control operation of the scrap removal system.

15. The system of claim 12 , wherein:
the base plate comprising a plurality of vacuum apertures;
the carrier transfer device comprises a vacuum table in fluid communication with the plurality of vacuum apertures and configured to apply a retention vacuum to the plurality of vacuum apertures to retain the film on the base plate; and
the controller is further programmed to control operation of the vacuum table.

16. The system of claim 12 , further comprising a film removal system configured to remove the film from the at least one composite ply using the film removal system after being formed over the at least a portion of the forming surface of the forming tool,
wherein the controller is further programmed to control operation of the film removal system.

17. The system of claim 12 , further comprising a positioning system configured to guide and selectively position the carrier transfer device relative to the lamination system and the transfer system,
wherein the controller is further programmed to control operation of the positioning system.

18. A method of fabricating a composite structure, the method comprising steps of:
selectively applying at least one composite ply to a ply support surface of a ply carrier using a lamination system, wherein the ply carrier comprises a base plate and a film positioned on the base plate that forms the ply support surface;
conveying the ply carrier from the lamination system to a transfer system using a carrier transfer device;
removing the ply carrier from the carrier transfer device and applying the at least one composite ply to at least a portion of a forming surface of a forming tool using the transfer system; and
forming the at least one composite ply over the at least a portion of the forming surface of the forming tool using a forming system.

19. The method of claim 18 , further comprising:
conveying the ply carrier from the lamination system to a trim system using the carrier transfer device;
selectively cutting the at least one composite ply into a predetermined shape using the trim system; and
conveying the ply carrier from the trim system to the transfer system using the carrier transfer device.

20. The method of claim 19 , further comprising removing a remnant of the at least one composite ply from the ply support surface using a scrap removal system, after the step of selectively cutting the at least one composite ply into a predetermined shape using the trim system.
