COMBINED COMPOSITES BASED ON POLYLACTIDE 3D MATERIALS AND POLYURETHANE
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.
