Fiber-optic Raman spectroscopy was used to monitor the curing of epoxy resins in situ for eventual application to polymer composite processing. A 200-pm diameter quartz fiberoptic sensor immersed in liquid resin was used to obtain Raman spectra for a concentration series of diglicidyl ether of bisph
## Abstract A novel cure sensor, based on the combination of fiberβoptic fluorometry and the viscosity/degreeβofβcure dependence of the epoxy resin fluorescence, was developed to provide a reliable lowβcost cureβmonitoring sensor for control of composite manufacturing. The capability of the firstβg
A methodology is reported for monitoring the evolution of isothermal physical properties of thermosetting systems with increasing conversion (cure). For this report, measurements of modulus vs. temperature of a single composite specimen were obtained on repetitive cooling and subsequent heating to s
