Abstract
A method for real-time determination of the percent cure of epoxies vi a in situ fiber-optic Raman spectroscopy has been developed. This meth od utilizes a probe design developed for real-time monitoring of polym er curing and multivariate analysis to interpret the data and determin e percent cure. This method was demonstrated to be reliable to +/-0.54 % of cure in laboratory samples over a 50-99% cure range. A preliminar y study measuring cure percentage in an industrial, glass-reinforced c omposite has been shown to be reliable to +/-0.82% in the 40-90% cure range.
