The 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.
