Description

Dynamic dielectric analysis (DDA) is an instrumental means for quantitative material evaluation and closed loop “smart” cure cycle control. DDA is particularly important to process control because it is one of only a few experimental techniques for conveniently studying the cure process continuously, that is, to examine the cure chemistry throughout the process of going from a monomeric liquid of varying viscosity to a crosslinked, insoluble, high temperature solid [1–3]. The key for achieving this goal is to relate the chemistry of the cure process to the dielectric properties of the polymer system by correlating time, temperature and frequency dependent dielectric measurements with other chemical characterization methods.
