Composite forming apparatus

1. A method comprising:

laying up a number of composite plies onto a base and overlapping onto a plate, wherein:

the number of composite plies is interleaved along a periphery with portions of a number of sheets laid up on the plate to form an overlap; and

the number of sheets is connected to the plate;

placing a drape directly over the number of composite plies and the number of sheets; and

lowering the plate connected to the number of sheets to form the number of composite plies around an edge of the base, wherein as the plate is lowered, the number of sheets is progressively pulled from between each of the number of composite plies.

2. The method of claim 1 further comprising:

drawing a vacuum on the number of composite plies and the number of sheets.

3. The method of claim 2 , wherein lowering the plate connected to the number of sheets is performed while the number of composite plies and the number of sheets is under the vacuum.

4. The method of claim 2 , wherein drawing the vacuum on the number of composite plies and the number of sheets comprises pulling a vacuum under the drape.

5. The method of claim 1 , wherein lowering the plate connected to the number of sheets pulls the portions of the number of sheets from between each of the number of composite plies.

6. The method of claim 1 further comprising:

placing the number of composite plies on a base having a cavity, wherein the plate is associated with the cavity, and wherein lowering the plate connected to the number of sheets forms the number of composite plies to the base.

7. The method of claim 6 , wherein forming the number of composite plies to the base includes forming a portion of the number of composite plies to the base within the cavity.

8. The method of claim 1 further comprising:

heating the number of composite plies to a forming temperature prior to lowering the plate.

9. A method comprising:

placing a first ply onto a base, the base having a number of cavities, wherein the first ply overlaps onto a plate;

placing a portion of a first sheet onto the first ply;

placing a second ply onto the first ply;

connecting the first sheet to the plate;

placing a drape directly over the first ply, the second ply, and the first sheet;

drawing a vacuum under the drape; and

lowering the plate, wherein the first sheet moves as the plate is lowered.

10. The method of claim 9 , wherein lowering the plate connected to the first sheet pulls the portion of the first sheet from between the first ply and the second ply.

11. The method of claim 10 , wherein lowering the plate forms the first sheet against the plate.

12. The method of claim 10 , wherein lowering the plate connected to the first sheet forms the first ply and the second ply to the base.

13. The method of claim 12 , wherein forming the first ply and the second ply to the base includes forming a portion of the first ply and a portion of the second ply to an edge of the base associated with a cavity of the number of cavities.

14. The method of claim 9 further comprising:

heating the first ply and the second ply to a forming temperature prior to lowering the plate.

15. A method comprising:

laying up a plurality of composite plies onto a base and a plate, wherein:

the plate is configured to move in a cavity;

the plurality of composite plies overlaps the plate;

the plate is disposed laterally adjacent the base;

the plurality of composite plies and a plurality of sheets are interleaved along a periphery of the base; and

the plurality of sheets is connected to the plate;

placing a drape over the plurality of composite plies and the plurality of sheets; and

lowering the plate in the cavity to form the plurality of composite plies around an edge of the base;

wherein, the plurality of composite plies and the plurality of sheets have:

a first respective configuration prior to lowering the plate;

a second respective configuration during lowering of the plate, the second respective configuration including the plurality of sheets bent away from the plate, the second respective configuration different than the first respective configuration; and

a third respective configuration after lowering the plate, the third respective configuration different than the second respective configuration, and the third respective configuration different than the first respective configuration.

16. The method of claim 15 , wherein, prior to lowering the plate, the plurality of composite plies and the plurality of sheets form an overlap in the periphery.

17. The method of claim 16 , wherein, after lowering the plate, the plurality of composite plies and the plurality of sheets are not overlapped.

18. The method of claim 15 , wherein the first respective configuration includes the plurality of composite plies and the plurality of sheets being substantially flat.

19. The method of claim 18 , wherein the second respective configuration further includes the plurality of composite plies bent toward the plate.

20. The method of claim 19 , wherein the third respective configuration includes:

the plurality of composite plies bent around an edge of the base and toward the plate; and

the plurality of sheets being substantially flat.
