Abstract
Induction heating is utilized to heat polymer matrix composites containing electrically conductive fibers. This is accomplished with an apparatus having a mold with first and second cores positioned to receive a workpiece therebetween and first and second induction coils mounted to the first and second cores, respectively. Each induction coil is encapsulated in a layer of non-electrically conductive material which is attached to a surface of the respective core. A thermal insulation layer is attached to each layer of material, and a skin layer is attached to each thermal insulation layer. Alternatively, the induction coils can be embedded in the corresponding mold core. In another alternative, a single helical induction coil can be disposed around the two mold cores.
