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.

ТECHNOLOGICAL FEATURES OF OBTAINING STARCH-CONTAINING POLYLACTIDE MATERIALS FOR 3D PRINTING

Polylactide composite materials with organic filler-modifier starch, inorganic filler -calcium carbonate and plasticizer - epoxidized soybean oil for 3D printing have been developed. On the basis of the modular deformation method of calculation the elastic-plastic and deformation properties of the developed modified polylactide materials are determined. The change of modulus of deformation, modulus of elasticity, modulus of high elasticity depending on the composition of the composite is revealed.

FEATURES OF STARCH MODIFICATION FOR THE CREATION OF POLYMER COMPOSITES

The physicochemical regularities of interactions in the starch-glycerol-epoxidized soybean oil system under the influence of ultrasound were investigated. On the basis of rheological curves, the effect of plasticizers on the viscosity of glycerin-starch systems was revealed, depending on the shear rate, time of exposure at temperature, and the nature of starch. On the basis of IR spectroscopic studies, the existence of interactions between the components of the system was confirmed.
