Abstract

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%).

对固化热固性合成树脂进行电脉冲处理

研究了纳秒电磁脉冲（NEMP）电脉冲处理前后固化合成热固性树脂的物理和机械特性：吸水性、表层能（表面张力）、拉伸强度。研究证实，用纳秒电磁脉冲对固化聚合物粘合剂进行电脉冲处理可有效提高材料强度并降低吸湿性。使用纳秒电磁脉冲辐照固化树脂的最佳辐照制度已经确定：脉冲重复频率为 1000 Hz，脉冲振幅为 15 kV，辐照持续时间为 10 分钟。使用纳秒电磁脉冲进行辐照后，样品的强度极限提高了（环氧树脂提高了 12.8%，乙烯基酯树脂提高了 18.6%，聚酯树脂提高了 21.1%），吸水率降低了（环氧树脂降低了 25.6%，乙烯基酯树脂降低了 21.6%，聚酯树脂降低了 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.
