摘要： An apparatus for thermoplastic welding includes at least one tool configured to support first and second thermoplastic composite parts in a first welding position having one or more joint lines between the first and second thermoplastic composite parts. The tool includes a plurality of induction coils. The apparatus further includes a susceptor removably positioned along the one or more joint lines. The susceptor is configured to heat the one or more joint lines when exposed to a magnetic flux generated by the plurality of induction coils to bond the first and second thermoplastic composite parts along the one or more joint lines. The apparatus also includes a susceptor removal device coupled to the susceptor and configured to remove the susceptor during bonding of the first and second thermoplastic composite parts.

摘要： An induction curing system comprises a slip sheet and a power supply. The slip sheet comprises a layup surface configured to receive a composite material, a tool interface surface configured to interface with an upper surface of a tool, a rigid body extending between the layup surface and the tool interface surface, and an induction coil circuit within the rigid body of the slip sheet. The induction coil circuit is configured to heat the layup surface to a temperature sufficient to cure the composite material. The induction coil circuit has a diameter selected to generate heat using a power supply having a frequency below 150 kHz. The rigid body is configured to support the composite material during transport of the composite material. The power supply is coupled with the induction coil circuit, the power supply is selected based on the diameter of the induction coil circuit.

摘要： A composite sandwich panel includes a first composite part and a second composite part. A plurality of stiffeners extend between the first and second composite parts. A fiberglass composite perimeter edge closeout is positioned along one or more edges of the first and second composite parts. The fiberglass composite perimeter edge closeout controls a magnetic flux to bond the first and second composite parts to the plurality of stiffeners.
