dc.description.abstract |
This communication concerns the treatment of dielectric data obtained from
experiments following the chemical hardening process (cure) in thermosetting
resins. The aim is to follow, in real time, the evolution of the individual
parameters of an equivalent electrical circuit that expresses the electrical
behavior of a curing thermoset. The article presents a methodology for the
sequential inversion of impedance spectra obtained in cure monitoring
experiments. A new parameter estimation technique based on genetic algorithms is
developed and tested using different objective functions. The influence of the
objective functions on the modelling performance is investigated. The new
technique models successfully spectra contaminated with high noise levels. The
introduction of regularization in the optimization function rationalizes the
effects of outliers usually detected in cure monitoring dielectric spectra. The
technique was successfully applied to the analysis of a series of spectra
obtained during the cure of an epoxy thermosetting resin. |
