The conducted studies have proven the possibility of the directed control of operational properties of epoxy composites, due to the addition of finely-ground ocher into their composition, and the use of microwave modification of the epoxy composition. The rational content of ocher as a modifying additive (0.5 parts by mass) and a filler (75 parts by mass) of the epoxy composition has been selected, which ensures the improvement of the studied complex of physical-mechanical properties. It has been proven that ocher affects the structure formation processes and the structure of the epoxy composite, thus increasing its thermal, heat and fire resistance. During the research, the application efficiency has been proven, and the optimal parameters of the microwave modification (power-350 W; duration-30 s) of epoxy compositions filled with ocher, which increase physical-mechanical characteristics of composites, have been selected.
已开展的研究证明，通过在环氧复合材料的组成中添加细磨赭石，并对环氧组合物进行微波改性，可实现对其操作性能的定向控制。已选择了赭石作为环氧组合物改性添加剂（质量分数为0.5份）和填料（质量分数为75份）的合理含量，这确保了所研究的物理机械性能复合体得到改善。已证明赭石会影响环氧复合材料的结构形成过程和结构，从而提高其耐热性、热稳定性和耐火性。在研究过程中，已证明了应用效率，并选择了填充赭石的环氧组合物微波改性的最佳参数（功率350W；持续时间30s），这些参数可提高复合材料的物理机械性能。
