Abstract:
Apparatus for making consolidated, reinforced resin matrix composites, comprising(a) a die set having at least two dies made of cast, insulative ceramic, each having a contoured mold surface defining a pressurizing cavity;(b) an induction coil having segments cast within at least one die and lie longitudinally adjacent in a proximity to the mold surface;(c) means for opening and closing the die set to permit access to the mold surface;(d) active cooling means associated with the coil for circulating coolant when the coil is energized;(e) a power supply electrically coupled with the coil for providing time-varying energy to the coil;(f) a susceptor, inserted within said cavity, responsive to the time varying energy of the coil for heating when the power supply is energized;(g) gas pressure means for applying a forming or consolidating pressure while the coil is energized and the die set is closed; and(h) optionally, a vacuum pump for evacuating a region around the composite when the coil is energized.
