polyurethane resin

 The features of obtaining combined polylactide composites based on 3D printed matrices and  polyurethane binders modified with starch and epoxidized soybean oil have been established. The features of the physical and mechanical properties of combined composites have been studied by constructing load-strain curves. Factors influencing the physical and mechanical properties of the obtained composites depending on the composition of the composition and the plane of load application have been identified. 

The peculiarities of the production and structure of combined composites based on polylactide 3D printed matrices and polyurethane resin were investigated. The physical and mechanical properties of the obtained composites were determined depending on the content of modifiers in the polyurethane resin. In particular, an increase in Brinell hardness and impact toughness of products based on 3D matrices filled with modified resin was revealed.
