Variable frequency microwave energy was successfully applied to uniformly heat thermoset polymer matrix composite (PMC) materials consisting of glass-reinforced isocyanate/epoxy mixtures as well as graphite fiber-reinforced epoxy. Results of a series of materials processed via variable frequency microwave energy are compared with computed results from numerical modeling techniques. A finite difference time domain (FDTD) technique provides 2-D models of the electric and thermal field distributions inside the microwave cavity as well as inside the processed materials. The materials` physical and chemical characteristics from the empirical trials are evaluated for both variable and fixed frequency irradiation.
