Effect of nanosecond electric pulse processing on thermodynamic properties of thermosetting synthetic resins

The paper presents the results of a study of the effect of nanosecond electromagnetic pulses (NEMP) treatment on some thermodynamic characteristics of polymers used in the production of fi berglass reinforced plastics. It was found that NEMP treatment of YD-128 epoxy resin, Polysystem VE-3701 LVP vinyl ester resin, and Polysystem YMI-100 polyester resin has a modifying eff ect. An increase in impregnation rate of epoxy resin treated with NEMP for a period of 0 to 15 minutes is noted. As for polyester and vinyl ester resins, their treatment with NEMP does not accelerate the impregnation process.
