The targeted curing of glass fiber-reinforced plastics (GFRP) is important to ensure the advantageous material properties. The use of RFID for curing monitoring is a completely new approach. This paper presents an experiment in which an RFID transponder has been integrated into GFRP and the Received Signal Strength Indicator (RSSI) has been measured during the curing process. The result shows that the RSSI can be used as an indicator for curing GFRP. The advantages of RFID technology compared to conventional methods for cure monitoring are the wireless application as well as the benefit, which an integrated RFID transponder generates in the further product life.
