Цель исследования. Получение композиционных материалов методом горячего прессования с различным процентным соотношением наночастиц диоксида титана и диоксида церия, исследование их фазового состава и микротвёрдости.Методы. Методом горячего прессования получены композиционные материалы с включением наночастиц диоксида титана и частиц диоксида церия с их различным процентным содержанием в образцах. Методом атомно-силовой микроскопии определен нанометровый размер частиц в порошке диоксида титана. Показано наличие частиц диоксида титана и диоксида церия в полученных композиционных материалах методом рентгеноструктурной дифрактометрии. Методом Виккерса установлено среднее значение микротвёрдости композиционных образцов.Результаты. Получены композиционные материалы диаметром 40 мм и толщиной 9 мм на основе акриловой смолы с различным процентным составом порошков диоксида церия и титана в образцах. Анализ АСМ-изображений порошка диоксида титана позволяет отметить наличие как наноразмерных частиц, так и их агломератов в нём. По результатам рентгеноструктурного анализа выявлено наличие частиц диоксида церия и наночастиц диоксида титана в композиционных образцах и отсутствия в них примесей других веществ. Определена фаза анатаз в TiO2. Установлено, что при добавлении в акриловую матрицу частиц диоксида церия и наночастиц диоксида титана микротвердость композиционных материалов увеличивается.Заключение. В данной работе описан способ получения композиционных материалов методом горячего прессования. Установлено, что значения микротвёрдости композиционных материалов увеличиваются от роста процентного содержания в них наполнителей. Рост микротвёрдости композиционных материалов предположительно обусловлен межмолекулярным взаимодействием смеси наполнителей и акриловой смолы между собой в процессе её плавления. 

Purpose of the study. Obtaining composite materials by hot pressing with different percentage ratios of Titanium dioxide and Cerium dioxide nanoparticles, studying their phase composition and microhardness.Methods. Composite materials with inclusion of titanium Dioxide nanoparticles and Cerium dioxide particles with their different percentage content in samples were obtained by hot pressing. The nanometer size of particles in titanium dioxide powder was determined by atomic force microscopy. The presence of titanium dioxide and cerium dioxide particles in the obtained composite materials was shown using X-ray diffractometry. The average value of microhardness of composite samples was determined by the Vickers method.Results. Composite materials with a diameter of 40 mm and a thickness of 9 mm based on acrylic resin with different percentage composition of Cerium dioxide and Titanium dioxide powders in the samples were obtained. Analysis of AFM images of titanium dioxide powder allows us to note the presence of both nanosized particles and their agglomerates in it. According to the results of X-ray structural analysis, the presence of cerium dioxide particles and titanium dioxide nanoparticles in the composite samples and the absence of impurities of other substances in them were revealed. The anatase phase in TiO2 was determined. It was found that when Cerium dioxide particles and titanium dioxide nanoparticles are added to the acrylic matrix, the microhardness of the composite materials increases.Conclusion: This paper describes a method for producing composite materials using hot pressing. It has been established that the microhardness values of composite materials increase with the growth of the percentage of fillers in them. The growth of the microhardness of composite materials is presumably due to the intermolecular interaction of the filler mixture and acrylic resin with each other during its melting.
