FIELD: polymer composition.
SUBSTANCE: polymer composition and methods for producing and using a composite based on it. Invention is used for manufacturing of a low-density material without the use of external pressure, including for obtaining completely closed 3D objects without technological holes inside. The polymer composition for the manufacture of a composite material includes thermoset plastics and thermally expandable polymer microspheres, which are selected in such a way as to ensure the joint process of curing of thermoset plastics and expansion of thermally expandable polymer microspheres, the exothermic reaction of which affects the temperature of the mixture of thermoset plastics and thermally expandable polymer microspheres by 5–10 °C.
EFFECT: provision of a polymer composition for manufacture and use of composite materials that have a low specific gravity with improved physical and mechanical characteristics.
