Abstract:
A first tooling die and a second tooling die are movable with respect to each other. The first tooling die and the second tooling die form a die cavity. The first tooling die and the second tooling die comprise a plurality of stacked metal sheets. A plurality of air gaps is defined between adjacent stacked metal sheets. A first smart susceptor material is within the die cavity and connected to the first tooling die. The first smart susceptor material has a first Curie temperature. A second smart susceptor material is within the die cavity and associated with the second tooling die. The second smart susceptor material has a second Curie temperature lower than the first Curie temperature. A flexible membrane is between the second tooling die and the first smart susceptor material. The flexible membrane is configured to receive pressure.
