Modeling the Heating of the Binder of Polymeric Composite Materials Using Microwave Radiation

One of the most important tasks in space-rocket manufacturing is to increase the performance, energy efficiency and quality of the polymer composite parts. A particularly challenging problem is curing the polymer binder in workpieces. Microwave volumetric heating can provide significant advantages compared to conventional curing techniques, provided that the microwave heating regimes are justified theoretically. The paper provides a solution to the problem of heating a cylindrical part from a polymer composite material. Physical and mathematical models of electromagnetic radiation transfer are developed within the framework of a multiscale approach. The models take into account the distribution of the electromagnetic field in the components of the composite’s constituents. The thermal state of the part is modeled for various microwave heating arrangements. It is shown that the most uniform heating is achieved in a rectangular chamber, with the part rotating along its axis.
