В работе выполнен синтез и проведено исследование структуры и свойств органо-неорганических оксида меди (CuO) и магнетит (Fe3O4)-содержащих эпоксидных композитов, поглощающих излучение в ближней инфракрасной области спектра. Метод. Синтез композитов осуществлен введением микропорошков CuO и Fe3O4 в жидкую эпоксидную композицию с последующей гомогенизацией смеси и ее полимеризацией. Исследование структуры и свойств органо-неорганических композитов проведено методами оптической микроскопии, инфракрасной спектроскопии, оптической спектроскопии, исследованием микротвердости материалов.</p></sec><sec><title>Основные результаты</title><p>Основные результаты. По данным, полученным на основании инфракрасных спектров поглощения, введение оксидных частиц снижает степень отверждения эпоксидного полимера на 20–28 %. Fe3O4-содержащие композиты демонстрируют относительно низкое (до 4,2 %) отражение света в спектральном диапазоне 1000–1100 нм, что соответствует проведенным оценочным расчетам. При введении микропорошков CuO и Fe3O4 в состав эпоксидного полимера его микротвердость может быть увеличена от 120 до 160 МПа. Обсуждение. Полученные в работе экспериментальные результаты могут служить основой для разработки органо-неорганических композиционных материалов для лазерной техники, поглощающих излучение в ближней инфракрасной области спектра.</p></sec></abstract><trans-abstract xml:lang="en"><p>Synthesis and study on structure and properties of organic-inorganic composites based on epoxy resin, CuO and Fe3O4 absorbing light in infrared part of spectrum was performed. The composites synthesis was performed by introduction of CuO and Fe3O4 micropowders into liquid epoxy composition with subsequent homogenization of the mixture and polymerization. The study on structure and properties of organic-inorganic composites was performed by methods of optical microscopy, infrared and visible spectroscopy, study on microhardness. According to the IR spectroscopy data, introduction of oxide particles leads to decrease in epoxy polymer degree of calcification. The composites containing Fe3O4 show relatively low light reflection until 4.2 % in the spectral range of 1000–1100 nm that corresponds to the theoretical estimation data. Incorporation of CuO and Fe3O4 micropowders into the epoxy polymer leads to an increase in microhardness from 120 to 160 MPa. Obtained experimental data can serve as the base for development of IR-absorbing organic-inorganic composites for laser technology.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>поглощение света</kwd><kwd>композит</kwd><kwd>эпоксидная смола</kwd><kwd>микропорошок</kwd></kwd-group><kwd-group xml:lang="en"><kwd>light absorption</kwd><kwd>composite</kwd><kwd>epoxy resin</kwd><kwd>micropowder</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Ting T.H.
