A method and apparatus for applying a force to an assembly comprising a layup mandrel and a composite part. The apparatus comprises a first gripper and a second gripper. The second gripper is spaced apart from the first gripper so as to define a space between the first and second grippers, the space
A method and apparatus for applying a force to an assembly comprising a layup mandrel and a composite part. The apparatus comprises a first gripper and a second gripper. The second gripper is spaced apart from the first gripper so as to define a space between the first and second grippers, the space configured to receive the assembly. An actuation system is positioned between the first and second grippers adjacent the space, the actuation system configured to separate the layup mandrel from the composite part by applying force.

1. An apparatus for applying a force to an assembly comprising a layup mandrel and a composite part, the apparatus comprising: a first gripper;a second gripper, wherein the second gripper is spaced apart from the first gripper to define a space between the first and second grippers, the space configured to receive the assembly; andan actuation system positioned between the first and second grippers adjacent the space, the actuation system comprising at least a first actuator, the actuation system configured to separate the layup mandrel from the composite part by applying force, wherein the first actuator is operatively coupled to an adjacent mandrel. 2. The apparatus of claim 1, further comprising a body comprising a central portion, a first end portion, and a second end portion,wherein the first gripper is located at the first end portion,wherein the second gripper is located at the second end portion, andwherein the actuation system is coupled to the central portion. 3. The apparatus of claim 1, wherein a position of the first gripper is adjustable. 4. The apparatus of claim 1, wherein a position of the second gripper is adjustable. 5. The apparatus of claim 1, wherein at least the first gripper comprises a plurality of holes, wherein a pin is configured to be inserted into one of the plurality of holes so as to secure the first gripper in a desired position. 6. The apparatus of claim 5, wherein the pin comprises a spring loaded pin. 7. The apparatus of claim 1, wherein the first gripper comprises a bearing surface configured to contact a surface of an assembly positioned in the space. 8. The apparatus of claim 1 wherein the first actuator comprises a first hydraulic actuator. 9. The apparatus of claim 8, wherein the actuation system comprises a second hydraulic actuator. 10. The apparatus of claim 9, wherein the actuation system further comprises a transfer block positioned between the first and the second hydraulic actuators. 11. The apparatus of claim 10, wherein the transfer block is configured to receive a force provided by at least the first hydraulic actuator so as to separate the layup mandrel from the composite part. 12. The apparatus of claim 1, wherein the first actuator is operatively coupled to the adjacent mandrel using a pin. 13. A method of separating a layup mandrel from a composite part using an apparatus for applying a force to an assembly comprising the layup mandrel and the composite part, the apparatus comprising: a first gripper; a second gripper, wherein the second gripper is spaced apart from the first gripper to define a space between the first and second grippers, the space configured to receive the assembly; and an actuation system positioned between the first and second grippers adjacent the space, the actuation system comprising at least a first actuator, the actuation system configured to separate the layup mandrel from the composite part by applying force, wherein the first actuator is operatively coupled to an adjacent mandrel, the method comprising: constraining the composite part in a stationary position;coupling the first actuator to the layup mandrel; andapplying force to a transfer block, wherein the first actuator comprises a piston, which moves in a first direction to contact the transfer block,whereby the layup mandrel is caused to move in a second, opposite direction away from the composite part. 14. The method of claim 13, wherein the layup mandrel comprises a first layup mandrel part and a second layup mandrel part, the method further comprising the step ofcoupling the first actuator to the first layup mandrel and a second actuator to the second layup mandrel. 15. The method of claim 13, wherein the first layup mandrel and the second layup mandrel are separated from the composite part simultaneously. 16. The method of claim 13, wherein the first layup mandrel is separated from the composite part before the second layup mandrel is separated from the composite part. 17. The method of claim 13, further comprising the step of hydraulically actuating the first actuator. 18. The method of claim 13, further comprising the step of adjusting a position of a first gripper so as to change a size of a space. 19. The method of claim 18, wherein at least the first gripper constrains the composite part in the stationary position. 20. The apparatus of claim 3, wherein the second gripper is in a fixed position.
