Patent number: 10994450Abstract: 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.Type: GrantFiled: April 8, 2020Date of Patent: May 4, 2021Assignee: The Boeing CompanyInventors: Marc R. Matsen, Lee C. Firth, Gregory A. Foltz, William C. Dykstra, Jennifer S. Noel

The panel further comprises a core sheet intercoupled between the first face sheet and the second face sheet. Each of the first and second face sheets is made of a material having a thermal expansion that is different from the thermal expansion of the other face sheet.Type: ApplicationFiled: January 22, 2020Publication date: September 10, 2020Applicant: The Boeing CompanyInventors: Marc R. Matsen, Lee C. Firth, David S. Nansen, Michael R. Zolnowski, Carey E. Wilkinson, Gregory A. Foltz

Patent number: 10743377Abstract: 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.Type: GrantFiled: December 14, 2017Date of Patent: August 11, 2020Assignee: The Boeing CompanyInventors: Marc R.
