One-Line Monitoring of the Curing Process of FRP

The knowledge of the cure situation during the production process of thermosetting material is of enormous importance. • Mid- and near- infrared (IR) spectroscopy in attenuated total reflectance (ATR) geometry are promising techniques for curing studies. • An IR/THz sensor system was developed to investigate its suitability for future online monitoring of curing processes in the production line.
