Paper Abstract

The processing of advanced fiber reinforced composites requires accurate data on the temperature and chemical composition of the resin system as a function of time. This paper reports on a preliminary study to evaluate two multi- functional sensor arrangements to facilitate in-situ chemical and temperature monitoring in epoxy resin-based thermosets. Sensor arrangements evaluated for chemical analysis include evanescent wave and transmission-based near-infrared spectroscopy; and for temperature monitoring optical fiber Bragg gratings. A comparative analysis was undertaken to ascertain the relative merits of each sensor configuration.
