Abstract
A heating apparatus and a method for using a heating apparatus for repairing composite structures. The heating apparatus includes a high temperature matrix having magnetic particles therein. The magnetic particles have a predetermined Curie temperature. The apparatus also includes a coil in communication with a power source. The coil is disposed adjacent the matrix and magnetic particles. The coil provides an alternating current sufficient to heat the magnetic particles up to about the predetermined Curie temperature. The method utilizes the uniform heat provided by the heating apparatus to bond a repair patch to a composite material.
