Electric Pulse Treatment of Cured Thermosetting Synthetic Resins
The physical and mechanical characteristics of cured synthetic thermosetting resins before and after electric pulse treatment with nanosecond electromagnetic pulses (NEMP) have been studied: water absorption, surface layer energy (surface tension), tensile strength. The efficiency of electric pulse treatment of cured polymer binders with NEMP to increase strength and reduce moisture absorption of materials has been confirmed. The optimal irradiation regime of cured resins with nanosecond electromagnetic pulses has been established: pulse repetition frequency of 1000 Hz, pulse amplitude of 15 kV, irradiation duration of 10 min. Implementing this irradiation regime with NEMP results in an increase in the strength limit of samples (for epoxy resin by 12.8%, for vinyl ester resin by 18.6%, for polyester resin by 21.1%) and a decrease in water absorption of samples (for epoxy resin by 25.6%, for vinyl ester resin by 21.6%, for polyester resin by 16.4%).
期刊介绍：
Inorganic Materials: Applied Research contains translations of research articles devoted to applied aspects of inorganic materials. Best articles are selected from four Russian periodicals: Materialovedenie, Perspektivnye Materialy, Fizika i Khimiya Obrabotki Materialov, and Voprosy Materialovedeniya and translated into English. The journal reports recent achievements in materials science: physical and chemical bases of materials science; effects of synergism in composite materials; computer simulations; creation of new materials (including carbon-based materials and ceramics, semiconductors, superconductors, composite materials, polymers, materials for nuclear engineering, materials for aircraft and space engineering, materials for quantum electronics, materials for electronics and optoelectronics, materials for nuclear and thermonuclear power engineering, radiation-hardened materials, materials for use in medicine, etc.); analytical techniques; structure–property relationships; nanostructures and nanotechnologies; advanced technologies; use of hydrogen in structural materials; and economic and environmental issues. The journal also considers engineering issues of materials processing with plasma, high-gradient crystallization, laser technology, and ultrasonic technology. Currently the journal does not accept direct submissions, but submissions to one of the source journals is possible.
