2.45 GHz perfluator heating module for industrial infiltration processes
A microwave (MW) perfluator heating module is a device for industrial resin infiltration processes. This MW system consists of a waveguide section, cylindrical holder of a Teflon hose for fluid injection, a MW source at 2.45 GHz and a control unit. It has been designed using full electromagnetic 3D numerical software tool CST Microwave Studio to provide an efficient energy transfer from the MW source to the liquid and to support an appropriate electromagnetic field structure for supperoior infiltration. This system has been optimized by experimental investigations for industrial production. In measurements with a vector network analyzer the system geometry has been adjusted to ensure the lowest reflections. Several prototypes have been successfully verified in standard as well as in sophisticated flow processes under industrial conditions. These high power tests have shown that the MW perfluator module is a flexible stand-alone unit that can be connected to existing product lines.
