For forming or consolidating organic matrix composites, for example, an organic matrix composite panel (106) is sealed between sheets of a susceptor material (100, 102) that is susceptible to induction heating. The susceptor sheets (100, 102) are heated inductively. The sheets in turn conduct heat to the organic matrix composite panel (106). When heated to the desired temperature, the composite panel (106) 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. |
