Abstract:
This work is an investigation of the mechanisms responsible for the microwave heating behavior of epoxies as applied to the cure of fiberglassEpoxy laminate structures. The problem is approached by the derivation of a mathematical relation for the rate of microwave heating in terms of electric field and material dependent parameters. The dielectric constant and loss tangent of gelled epoxy samples are measured and reported as functions of frequency and temperature. this information is used to develop a theoretical model for the microwave heating behavior of an epoxy during cure. The results of actual high power heating experiments are compared with the theoretical predictions. Physical mechanisms responsible for the observed behavior are proposed.
