Анализировали влияние на структуру и физико-механические свойства 50 %-го наполнения эпоксидной смолы исходными и водообработанными цементом и гипсом. Установлено, что образцы с водоотвержденными наполнителями характеризуются повышенными модулем упругости, огне- и термостойкостью, стойкостью к органическим растворителям. Методами оптической и СЭМ-микроскопии выявлено различие в их структуре по сравнению с исходными композитами. При этом заметного влияния на прочностные характеристики обычной термообработки (50 – 60 °C) не отмечено. После прогрева при 250 °C для наполненных композитов зафиксированы эффекты термоупрочнения и термопластификации — существенного роста прочности и пластичности при сжатии, микротвердости и стойкости к истиранию. Полученные результаты могут быть использованы при создании полиэпоксидных материалов с новыми свойствами, необходимыми для решения ответственных прикладных производственных задач.</p></abstract><trans-abstract xml:lang="en"><p>The goal of the study is to compare the properties of epoxy composites with initial and water-treated (hydrated) water-hardening binders (gypsum and cement). The effect of 50% filling of ED20 epoxy resin with initial and water-treated binders (cement and gypsum) on the strength of composites, their structure and physicomechanical properties is considered. An increase in such indicators as the elastic modulus value, fire- and heat resistance, as well as the resistance to organic solvents was observed. Optical and SEM microscopy revealed a difference in their structure compared to the original composites. However, there was no noticeable effect on the strength characteristics of conventional heat treatment (50 – 60°C). After heating at 250°C, the effect of thermal hardening (and thermoplasticization) was observed for filled composites: a significant increase in the compressive strength (and plasticity), microhardness, and abrasion resistance, compared to an unfilled polymer. The results obtained can be used to develop polyepoxide materials with new properties necessary for solving important production applications.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>эпоксидный композит</kwd><kwd>гипс</kwd><kwd>цемент</kwd><kwd>морфология</kwd><kwd>прочность при сжатии</kwd><kwd>изгиб</kwd><kwd>микротвердость</kwd><kwd>термоусиление</kwd><kwd>термопластификация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>epoxy composite</kwd><kwd>gypsum</kwd><kwd>cement</kwd><kwd>morphology</kwd><kwd>compressive strength</kwd><kwd>bending</kwd><kwd>microhardness</kwd><kwd>thermal strengthening</kwd><kwd>thermoplasticization</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">Воронков А.
