Abstract
A method for heating a composite comprising a nonconductive material that is a thermoplastic or a thermoset reinforced with conductive materials such as carbon fibers, by incorporating coupling particles in the structure. The structure is oriented in the plane of a magnetic field induced at frequencies from 3 kHz to 7 MHz, whereby the coupling particles respond as susceptors to the induced magnetic field and are preferentially heated (carbon fibers are not heated).
