A method for manufacturing composite parts. A temporary removal layer may be placed on an inner mold line tool. A composite material may be laid up on the inner mold line tool for a composite part. The inner mold line tool may be positioned with the composite part inside an outer mold line tool. The composite part and the temporary removal layer may be transferred from the inner mold line tool to the outer mold line tool. The inner mold line tool and the temporary removal layer may be removed from inside of the outer mold line tool after transferring the composite part and the temporary removal layer to the outer mold line tool.

1. A method for manufacturing composite parts, the method comprising: placing a temporary removal layer on an inner mold line tool;laying up a composite material on the inner mold line tool for a composite part;positioning the inner mold line tool with the composite part inside an outer mold line tool;transferring the composite part and the temporary removal layer from the inner mold line tool to the outer mold line tool; andremoving the inner mold line tool and the temporary removal layer from inside of the outer mold line tool after transferring the composite part and the temporary removal layer to the outer mold line tool and before curing the composite part on the outer mold line tool. 2. The method of claim 1 further comprising: installing a vacuum bag system over the composite part on the outer mold line tool after removing the inner mold line tool and the temporary removal layer. 3. The method of claim 2 further comprising: curing the composite part on the outer mold line tool with the vacuum bag system. 4. The method of claim 1, wherein the laying up step comprises: laying up a plurality of layers of composite fabric on the inner mold line tool to form a laminate for the composite part. 5. The method of claim 1, wherein the positioning step comprises: moving the inner mold line tool inside of the outer mold line tool. 6. The method of claim 5, wherein the inner mold line tool is concentric with the outer mold line tool when the inner mold line tool is moved inside of the outer mold line tool. 7. The method of claim 1, wherein the outer mold line tool has a base part and a top part, and wherein the positioning step comprises: moving the inner mold line tool over the base part; andplacing the top part on the base part with the inner mold line tool over the base part. 8. The method of claim 1, wherein the temporary removal layer is a bag and wherein the transferring step comprises: securing the bag to the outer mold line tool;applying a vacuum to the composite material to cause the composite material to move to the outer mold line tool from the inner mold line tool. 9. The method of claim 1, wherein the temporary removal layer is a film and wherein the transferring step comprises: securing the film to the outer mold line tool;applying a vacuum to the composite material to cause the composite material to move to the outer mold line tool from the inner mold line tool. 10. The method of claim 1, wherein the inner mold line tool comprises a plurality of tool parts and wherein the removing step comprises: disassembling the plurality of tool parts for the inner mold line tool to form a plurality of disassembled tool parts; andremoving the plurality of disassembled tool parts from inside of the outer mold line tool. 11. The method of claim 1, wherein the inner mold line tool comprises an inflated bladder wrapped around a mandrel and wherein the removing step comprises: deflating the bladder; andremoving the mandrel from the inside of the outer mold line tool after deflating the bladder. 12. The method of claim 1, wherein the inner mold line tool comprises a vacuum bag enclosing an open cell foam wrapped around a mandrel and wherein the removing step comprises: evacuating the vacuum bag; andremoving the mandrel from the inside of the outer mold line tool after evacuating the vacuum bag. 13. The method of claim 1 further comprising: placing a number of elements on the composite part on the outer mold line tool. 14. The method of claim 13, wherein the composite part is a one piece composite fuselage section and wherein the number of elements is selected from at least one of a number of stringers and a number of doublers. 15. The method of claim 1, wherein the inner mold line tool is an expandable tool and wherein the transferring step comprises: expanding a surface of the expandable tool from a retracted state to an expanded state;securing the temporary removal layer to the outer mold line tool; andapplying a vacuum to the composite part. 16. The method of claim 1 further comprising: placing a number of elements on a temporary removal layer on the inner mold line tool;transferring the elements to the outer mold line tool using the temporary removal layer. 17. The method of claim 1, wherein the composite part is for an object selected from one of a mobile platform, a stationary platform, a land-based structure, an aquatic-based structure, a space-based structure, an aircraft, a surface ship, a tank, a personnel carrier, a train, a spacecraft, a space station, a satellite, a submarine, an automobile, a power plant, a bridge, a dam, a manufacturing facility, and a building. 18. A method for manufacturing a one piece composite fuselage section for an aircraft, the method comprising: placing up a temporary removal layer on an expandable tool;laying up a plurality of layers of composite fabric on the expandable tool to form a laminate for the one piece composite fuselage section;positioning the expandable tool with the one piece composite fuselage section inside an outer mold line tool;transferring the one piece composite fuselage section and the temporary removal layer from the expandable tool to the outer mold line tool by expanding a surface of the expandable tool from a retracted state to an expanded state, securing the temporary removal layer to the outer mold line tool, and applying a vacuum to the one piece composite fuselage section;removing the expandable tool and the temporary removal layer from inside of the outer mold line tool after transferring the one piece composite fuselage section and the temporary removal layer to the outer mold line tool by disassembling a plurality of tool parts for the expandable tool to form a plurality of disassembled tool parts and removing the plurality of disassembled tool parts from inside of the outer mold line tool;placing a number of elements on the composite part on the outer mold line tool;installing a vacuum bag system over the composite part on the outer mold line tool after removing the expandable tool and the temporary removal layer; andcuring the composite part on the outer mold line tool with the vacuum bag system. 19. The method of claim 18, wherein the positioning step comprises: moving the expandable tool inside the outer mold line tool such that the expandable tool is concentric with the outer mold line tool when the expandable tool is moved inside of the outer mold line tool. 20. The method of claim 18, wherein the outer mold line tool has a base part and a top part, and wherein the positioning step comprises: moving the expandable tool over the base part; and placing the top part on the base part with the expandable tool over the base part.
