Abstract: Disclosed herein are induction heating cells and methods of using these cells for processing. An induction heating cell may be used for processing (e.g., consolidating and/or curing a composite layup having a non-planar portion. The induction heating cell comprises a caul, configured to position over and conform to this non-planar portion. Furthermore, the cell comprises a mandrel, configured to position over the caul and force the caul again the surface of the feature. The CTE of the caul may be closer to the CTE of the composite layup than to the CTE of the mandrel. As such, the caul isolates the composite layup from the dimensional changes of the mandrel, driven by temperature fluctuations. At the same time, the caul may conform to the surface of the mandrel, which can be used to define the shape and transfer pressure to the non-planar portion.

Abstract: Systems and methods are provided for creating precursors for consolidating composite parts. One embodiment is a method for forming a metallic structure. The method includes forming a precursor for a pressure membrane that includes a contour having a linearized length corresponding with a linearized length of a surface of a forming tool. The method also includes affixing a perimeter of the precursor to a perimeter of a base member, leaving a volume between the base member and the precursor, altering a shape of the precursor at a superplastic temperature by forcing the precursor into complementary contact with the surface of the forming tool, and setting the shape of the precursor while the precursor is held in complementary contact.

Abstract: Heating apparatus and methods for thermally processing a part including improved control of temperature. A thermal management system is coupled to a back surface of a table thermally coupled to an inductive heating circuit. The thermal management system includes a chamber defining an interior space, at least one cooling fin disposed within the chamber, an inlet extending through the chamber and fluidly communicating with the interior space, and an outlet extending through the chamber and fluidly communicating with the interior space. In some applications, an air source fluidly communicates with the inlet and is selectively operable to generate an air flow through the chamber, so that the thermal management system may be selectively operated in an insulator mode and a cooling mode.

Abstract: Provided are induction heating cells including pressure bladders used for supporting dies and methods of using these induction heating cells. A pressure bladder may be disposed between a die and a bolster of the cell. Even when the bolster is deformed during operation of the cell, the pressure bladder continues to provide uniform support to the die thereby preserving integrity of the die and prevents its cracking or braking. As such, the cell may be operated at a higher processing pressure inside the cavity formed by the die without further strengthening the bolster. The bolster is allowed to deform without compromising the integrity of the die. The deformation of the bolster is compensated by the shape change of the pressure bladder. The number and/or position of the bladders in the cell may depend on the shape of processed parts.

Abstract: Disclosed are induction heating cells comprising tensioning members with non-magnetic metal cores. Also disclosed are methods of operating such cells, for example, to process composite parts. The non-magnetic metal cores of the tensioning members provide excellent tensile strength. Furthermore, the non-magnetic metal cores allow forming long tensioning members leading to large induction heating cells for processing large composite parts, such aircraft fuselage parts, wing parts, and the like. The diameter of these non-magnetic metal cores is less than the induction heating threshold for magnetic fields used during operation of the cells, which ensures limited or no interaction of the cores with the magnetic fields. The cores can be arranged into a tensioning member extending through and compressing the die of an induction heating cell. When multiple cores are used, these cores are electrically insulated from each other, e.g., using an insulating shell or spacing these cores away from each other.

Abstract: A shim assembly includes a shim material configured to be positioned between a first component and a second component. A wire is in contact with the shim material. The wire is configured to heat the shim material to above a predetermined temperature, and the shim material becomes moldable above the predetermined temperature such that the shim material is able to conform to the first component and the second component.

Abstract: A system for inductively heating a workpiece may include an induction coil, at least one susceptor face sheet, and a current controller coupled. The induction coil may be configured to conduct an alternating current and generate a magnetic field in response to the alternating current. The susceptor face sheet may be configured to have a workpiece positioned therewith. The susceptor face sheet may be formed of a ferromagnetic alloy having a Curie temperature and being inductively heatable to an equilibrium temperature approaching the Curie temperature in response to the magnetic field. The current controller may be coupled to the induction coil and may be configured to adjust the alternating current in a manner causing a change in at least one heating parameter of the susceptor face sheet.
