EFFECTS OF THE HIGH FREQUENCY ELECTROMAGNETIC FIELD ON THE EPOXY RESIN PROPERTIES

Abstract

In the paper were performed comparative studies on properties and kinetics of physical and mechanical hardening of epoxy resins subjected to the action of the high frequency and conventional electromagnetic field. The epoxy resins tested for this study are P722 and P722M. The Diaminodiphenyl sulfone was used as a hardener in the preparation of both systems undergoing experiments. These experiments were performed in isothermal and non-isothermal conditions. In both cases there was a significant increase in the fractional conversion of the microwave treated samples compared to the conventionally treated samples.
