Abstract

A machine and a method for forming composite materials are provided. The machine includes a frame and at least one forming beam attached to the frame, the at least one beam being arranged to align with a mandrel. The forming beam is pivotally segmented into at least two segments to conform to the shape of the mandrel, or alternately is bendable to conform to the shape of the mandrel. The mandrel is receivable within the frame in alignment with the forming beam. An apparatus is also provided to position a composite charge over the mandrel, and to position the mandrel within the frame. A further apparatus is provided to transport the mandrel, and to urge the mandrel toward the forming beam, forming a composite charge.

Claims

1. An apparatus for forming composite materials, the apparatus comprising:

a frame;

at least one beam attached to the frame, the at least one beam being segmented longitudinally into at least two segments, the at least two segments being adjustably and reconfigurably arrangeable along a length of the beam with respect to each other to form a shape for forming a composite charge; and

a mandrel, having a first surface, the mandrel being receivable within the frame in alignment with the at least one beam, the mandrel being arranged to form the composite charge when the mandrel is received within the frame;

wherein the at least one beam includes a forming device that is arranged to urge the composite charge against the mandrel, wherein the forming device includes a forming bladder.

2. The apparatus of claim 1, wherein the at least two segments are pivotably attached to each other.

3. The apparatus of claim 1, wherein the at least two segments are independently positionable.

4. The apparatus of claim 1, further comprising at least one support that is attached to the frame and arranged to support a portion of the composite charge that overhangs the mandrel substantially parallel with the first surface.

5. The apparatus of claim 1, further comprising at least one positioning device that is attached to the frame and arranged to position the composite charge against the mandrel.

6. The apparatus of claim 5, wherein the positioning device includes a projector that is arranged to project an indicator onto the mandrel.

7. The apparatus of claim 1, further comprising at least one pulling device that is attached to the frame and arranged to pull the composite charge over the mandrel.

8. The apparatus of claim 1, further comprising at least one heater that is attached to the frame and arranged to heat a portion of the composite charge that overhangs the mandrel.

9. The apparatus of claim 1, further comprising a moving device that is arranged to transport the mandrel toward the frame and urge the mandrel against the beam.

10. An apparatus for forming composite materials, comprising:

a frame;

at least one beam attached to the frame, the at least one beam having a length, the at least one beam being adjustably and reconfigurably conformable along the length into a shape for forming a composite charge;

a mandrel having a first surface, the mandrel being receivable within the frame in alignment with the at least one beam, the mandrel being arranged to form the composite charge when the mandrel is received within the frame; and

a lifting device configured to raise the mandrel at least partially into the frame.

11. The apparatus of claim 10, wherein adjustably and re-configurably conformable along the length includes flexibly conformable.

12. An apparatus for forming composite materials, the apparatus comprising:

a frame;

at least one beam attached to the frame, the at least one beam being longitudinally segmented into at least two segments, the at least two segments being adjustably orientable with respect to each other to define a variety of non-linear segmented longitudinal axes;

a mandrel with a first surface, the mandrel receivable within the frame in alignment with the at least one beam, the mandrel being arranged to form a composite charge;

a pulling device movably attached to a frame to pull a composite charge to a predetermined location on the mandrel;

an indexing device arranged to stop the pulling device when the composite charge is at the predetermined location on the mandrel; and

a transport device, arranged to transport the mandrel and lift the mandrel into the frame.

13. The apparatus of claim 12, further comprising at least one support attached to the frame and arranged to support a portion of the composite charge that overhangs the mandrel substantially parallel with the first surface.

14. The apparatus of claim 12, further comprising at least one heater that is attached to the frame and arranged to heat a portion of the composite charge that overhangs the mandrel.

15. The apparatus of claim 12, wherein the at least one beam includes a forming bladder arranged to urge the composite charge against the mandrel.

16. The apparatus of claim 12, wherein the mandrel defines a mark used for positioning the indexing device.

17. An apparatus for forming a composite material, comprising:

at least one elongated beam adjustably conformable along its length;

an elongated mandrel having a forming surface configured to cooperate with the at least one elongated beam to form the composite material; and

a lifting device configured to raise the mandrel to position the forming surface proximate the at least one elongated beam.

18. The apparatus of claim 17, further comprising a frame coupled to the at least one elongated beam and configured to position the at least one elongated beam over the mandrel and oriented to cooperate with the forming surface.

19. The apparatus of claim 17, wherein the at least one elongated beam includes an inflatable member configured to urge the composite material into engagement with the forming surface of the mandrel.
