Abstract
In prvious publications, we described a technique based on fluorescence spectrocopy to monitor resin temperature during processing. The method consists of using optical fiber sensors to monitor fluorescence from a fluorescent dye that has been doped into the processed resin. Temperature is derived from temperature induced changes in the fluorescence spectrum. In practice, a temperature calibration function is obtained from the temperature dependence of the ratio of fluorescence intensities at two wavelengths. In this paper, we address several experimental design issues: (a) the supportive role of fluorescence anisotropy maesurements to the measuring concept, (b) the experimental setup used for non-contact measurements during capillary rheometer testing, and (c) molecular level environmental issues that arise during reactive processing and temperature profiling.Citation
