UV and Fluorescence Techniques for Characterization of Cure Processes in Polymersand Composites

摘要

The research on the development and application of sensitive optical techniquesfor characterization of cure processes in polymers and composites will be described. The first approach to be discussed is the route of the extrinsic reactive fluorophoric sensors, which were added in small amount, either to mimic the curing agent or the monomer. The second approach to be described is the UV signals for cure characterization of polymers and composites such as diamine-cured epoxy, polyimide, polyurethane, PMMA, and polystyrene. For in-situ characterization during the actual processing step, the development of fiber-optic fluorescence or UV reflection attachments will be described. jg.
