Study of the Operating Properties of Hardened Polymer Binders after Electric Impulse Treatment

Results of an experimental study of the effect of electrophysical treatment of hardened synthetic thermosetting resins on strength and water absorption are presented. A favorable effect of increasing strength and reducing water absorption capacity of hardened resin specimens studied after irradiation with nanosecond electromagnetic pulses is confirmed by experiment. A rational irradiation regime for cured resins is established during which for all the resins studied a maximum increase in strength and a reduction in water absorption are observed.
