Use of RFID tags for monitoring resin flow and investigation of their influence on the mechanical properties of the composite

摘要

In this study, we integrated RFID tags into glass epoxy composites. The RFID tag signal was monitored during resin infiltration and a correlation between resin arrival and a change in the RFID signal could be found. The impact of integrated sensors on the mechanical strength of the composite was investigated. The tensile strength of the composite is unaffected by integrated sensors, while the bending strength is reduced, however, bending deflection is greater in the samples containing sensors, thus avoiding an onset of catastrophic failure at a lower bending deflection in the samples with integrated sensor than in the samples without.
