CORRELATION OF THE DIELECTRIC PROPERTIES OF AN EPOXY RESIN WITH THE DEGREE OF CURE

Amke Eggers (Clausthal University of Technology) Dilmurat Abliz (Clausthal University of Technology) Gerhard Ziegmann (Clausthal University of Technology) Dieter Meiners (Clausthal University of Technology)

 

DEA can monitor the cure of a resin. Molecular alterations during the cure change the permittivity. From DSC measurements the degree of cure is fitted, which can be correlated with the DEA measurements by knowing the time lapse of both experiments.
