Heating of a composite of periodic structure in a high-frequency electromagnetic field

The properties of composites are improved with simultaneous simplification of production processes by the energy of an electromagnetic field of super-high frequency (SHF) in the drying and solidification stage. A unidirectional carbon fiber composite on solidified epoxy resin with regular arrangement of fibers is used as the model object to solve the problem encountered during volume heating. The composite is simulated by an ideal periodic medium that is a combination of periodicity cells with a small characteristic size compared with the body dimensions and with the length of electromagnetic waves that heat the composite. The proposed mathematical model is used to predict temperature fields under SHF heating and to determine admissible SHF regimes.
