Abstract Fiber composite components play an important role in the turnaround in energy policy as well as in stopping global warming. Therefore, it is essential to improve the manufacturing efficiency of these components. RFID technology is spreading to digitize and organize processes in production and logistics more efficiently. Since cure monitoring is a crucial factor in the manufacturing of composite components, the question arises whether the RFID technology is applicable for cure monitoring. This paper presents two methods of how an into glass fiber-reinforced plastics integrated RFID transponder could monitor the curing. Following the assumption that the change in permittivity of the glass fiber-reinforced plastic during curing influence the RFID signal, experiments in a measuring chamber (low-interference environment) were conducted. It was investigated whether the optimal response frequency of the integrated RFID transponder changes and whether the received signal strength indicator (RSSI) changes at a specific frequency during curing. As a reference method, the dielectric analysis as a well-known method for cure monitoring was used and compared with the RFID measurements. The results indicate that the optimal response frequency remains constant but the RSSI increases and possess a very high linear correlation with the measurement of the dielectric analysis in a low-interference environment. Consequently, the RFID technology is applicable to monitor the curing of glass fiber-reinforced plastics by measuring the RSSI in a low-interference environment.

1 Introduction In the past years, a continuous increase of the production volume of fiber-reinforced plastics (FRP) can be observed [1]. Reasons for the increase are that these materials play a major role in the turnaround in energy policy, as they are an essential part of wind turbines, and in stopping global warming. The pressure to reduce CO2 emissions is leading to increased efforts to make aircrafts, cars, trucks, and the like, more lightweight. FRP offer advantageous material properties for lightweight construction [1, 2].

In order to achieve the advantageous material properties, it is essential to cure the components in a targeted manner. Cure monitoring can improve both the quality and efficiency of the curing process of FRP [3]. Thus, there are many current research activities to enhance t
