Torsion Impregnated Cloth Analysis (TICA) of Epoxy Cure

Abstract

The technique of Torsion Impregnated Cloth Analysis (TICA) has been developed to allow continuous monitoring of the cure behavior of thermoset systems. Epoxy 3501-A has been used as the material in the feasibility study. The thermal scan of an incompletely cured epoxy specimen has shown that further curing effect during experimentation cannot always be ignored. The cure phase diagram and an isocure state curve have been constructed from the experimental results. Combining both results, it is concluded that an epoxy sample cured at 135 deg C for 5 hours will have an intrinsic cured glass transition of 158 deg C.
