Item type:Наукова стаття, Intensification of the formation process of sodium sulfate-modified biocomposite materials based on the glutinous matrix(Kharkiv: Institute of Single Crystals of the National Academy of Sciences of Ukraine, 2023) Sadova, Oksana; Kashytskyi, VitaliiThe influence of the modifying additive (sodium sulfate) on the heat treatment regime of the biocomposition in the mold investigated in the article. The optimal content of sodium sulfate in the biocomposite material was determined. The influence of the content of the modifying additive on the compressive strength of biocomposites structured at different temperatures has studied. The optimal parameters of the thermal field temperature and the duration of heat treatment of the biocomposition for the given content of the additive, which provides the maximum values of mechanical characteristics, are determined. It established that the modifying additive with optimal content is able to increase the intensity of structuring of biopolymer binder. This consists in the rapid transition of the glutin binder from the gel state to the solid state with the formation of physicochemical bonds due to the removal of excess moisture under the influence of temperature. Fractograms of the fracture surface of biocomposites containing sodium sulfate analyzed.Item type:Монографія, Properties and formation technology of glutinous biocomposite materials(Boston: Primedia eLaunch, 2023) Sadova, Oksana; Kashytskyi, VitaliiThe monograph presents the general characteristics and classification of biocomposite materials based on natural components, their advantages and scope of application are indicated. The mechanical properties of biocomposite materials based on a glutinous matrix and plant fillers were studied. The content of components was optimized. The formation modes of biocomposites with processing of the composition in physical fields were determined. The technology of recycling glutinous biocomposite products by thermo-mechanical processing of secondary raw materials has been developed. The monograph is intended for specialists in materials science of polymer composites and biocomposite materials. It will also be useful for graduate students, students, materials scientists, technologists and engineers of technical specialties.
