Monitoring Composites with Optical Fiber Sensor Systems



Richard~undefined~undefined~undefined~undefined~undefined Parnas, Joy Dunkers, R A. Neff


An inexpensive optical fiber has been interfaced with high-speed fluorescence and near infrared spectrometers to provide real-time monitoring of fast-reacting systems. Cure monitoring measurements were conducted in high volume fraction, glass reinforced composites with both an epoxy-amine system and a fast curing (<3 min gel time) polyurethane-isocyanurate system. Optical theory was applied to understand the response of evanescent wave optical fiber sensors.
