FIELD: glass fibers.
SUBSTANCE: method for producing dressed glass fibers, and polyesterimide composites based on them with improved values of the elasticity modulus and tensile strength, intended as structural polymeric materials. The group of inventions can be used in the production of structural products in 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' -diaminodiphenylpropane and polyetheretherketone based on 4,4'-dioxydiphenylpropane and 4,4' -difluorodiphenylketone. A polyesterimide composite is also proposed.
EFFECT: increasing the tensile strength and elasticity of a polyesterimide composite containing dressed glass fiber.
