摘要:
Sesceptor sheets are selected so that their magnetic permeability decreases to unity at approximately the desired operating temperature thereby limiting heating to this "Curie temperature" and providing substantial uniformity of temperature in the panel Preferably, the susceptor includes multiple layers, such as a first metal having a relatively lower Curie temperature, a thin foil of copper in contact with the surface of the first sheet, and a second metal having a relatively higher Curie temperature. Such a susceptor allows thermal control at two spaced set points defined by the Curie temperatures.

For forming or consolidating organic matrix composites, for example, an organic matrix composite panel is sealed between sheets of a susceptor material that is susceptible to induction heating. The susceptor sheets are heated inductively. The sheets in turn conduct heat to the organic matrix composite panel. When heated to the desired temperature, the composite panel is consolidated and/or formed. In the present invention, the susceptor sheets are selected so that their magnetic permeability decreases to unity at approximately the desired operating temperature thereby limiting heating to this "Curie temperature" and providing substantial uniformity of temperature in the panel. Of course, the concept applies to other induction heating operations for metals including SPF, brazing, annealing, heat treating, bonding, hot pressing, and the like.

Our induction heating workcell permits rapid and controlled heating and cooling of a workpiece within a wide temperature range. The induction workcell allows us to combine manufacturing operations, like SPF, brazing, and annealing, into a single heating cycle to save time, energy, capital, touch labor, and factory space. Superplastic forming (SPF) and brazing occur at temperatures that differ by about 150.degree.-200.degree. F. (85.degree.-105.degree. C.) or more as do SPF and .beta.-annealing of titanium. We can combine these operations into an economical single cycle in which both operations are done during a single heating of the press Multisheet SPF parts with braze joints at selected locations are made by (a) heating a multisheet pack to its superplastic forming range below the melting point of the braze alloy, (b) superplastically forming the pack at the SPF temperature to form the sheets and to define braze joints having unmelted braze alloy, (c) increasing the temperature to the braze temperature of the braze alloy, and (d) cooling the pack below the superplastic range to freeze the braze alloy in the braze joint.

摘要:
A method of forming a skin-foam-substrate type structure particular suitable as an automobile trim component. The method comprises supplying a polymer resin containing a chemical foaming agent and including metal particles capable of inductive heating, that is positioned between a polymeric skin and substrate, followed by inductive heating to cause foaming of the polymeric resin. The foamed polymer resin adheres to the skin and substrate.
