摘要

The peculiarities of obtaining combined products based on thermoplastic polylactide matrices and thermoreactive polyurethane resin are investigated. Depending on the component and quantitative composition, the factors affecting the physicomechanical properties of the obtained composites are identified. In particular, an increase in Brinell hardness and impact toughness of 3D matrices filled with resin is noted. The pile-up parameter for the developed materials is determined. The effect of modifiers (native starch and epoxidized soybean oil) on the elastoplastic properties and hardness of polyurethane resin is studied.
