FIELD: glass fibers.
SUBSTANCE: method for obtaining dressed glass fibers, and polyesterimide composites filled with them with improved glass transition temperatures, intended as structural polymeric materials in additive techniques. The group of inventions can be used in the products manufacture using additive techniques. The method for obtaining dressed glass fibers includes applying a dressing composition from a solution followed by drying. Dressing composition contains 4,4' -dioxidiphenyl sulfon in acetone. A polyesterimide composite is also proposed.
EFFECT: increasing of the glass transition temperature of a polyesterimide composite containing a finished glass fiber.
