  • Description: The results of research of physical and mechanical characteristics of the plate composite material obtained from birch wood after its processing by the method of explosive autohydrolysis are shown. Before barothermal treatment, the wood was impregnated with an aqueous solution of hydrogen peroxide. The composite material is made from hydrolyzed wood pulp by hot pressing without adding binders. It was found that the properties of the composite material depend on the amount of hydrogen peroxide and the rigidity of the barothermal treatment conditions. Each of the modes of barothermal treatment corresponds to a certain value of the amount of hydrogen peroxide, when using which the density of the material reaches the maximum value. The dependence of the bending strength of a composite material obtained using different amounts of hydrogen peroxide is characterized by the presence of an extremum point. At this point, the strength value is the maximum. Further increase in the amount of hydrogen peroxide is accompanied by a deterioration in strength characteristics. It is suggested that the effect is a consequence of the dominance of destructive processes over the processes of intermolecular crosslinking when using a large amount of hydrogen peroxide.
