Fiber reinforced polymers face growing interest in automotive, avionic and other engineering industries. Due to its high strength to mass ratio those materials can provide significant energy savings in various applications, although the production of those materials is still very energy consuming. One potential technology to reduce the energy consumption in production is the application of high power microwave technology in the curing process. For a successful system and process design profound knowledge about the dielectric properties of the resin and its change during chemical reaction is inevitable. Therefore, a test set for temperature dependent dielectric measurements at 2.45 GHz, based on the waveguide transmission and reflection method, has been developed. Epoxy resins with different catalysts and fillers were investigated and a model for description of the curing kinetics based on the dielectric data was developed. The so estimated curing state was validated by use of DSC data.
