METHOD OF PRODUCING POLYMERIC COMPOSITE MATERIALS Russian patent published in 2017 - IPC C09C3/04 C09C3/12 C08J5/08 B32B17/10 

FIELD: chemistry.

SUBSTANCE: composite material is produced by forming a fibrous roving base in the amount of 90-100 wp and its impregnation with a polymeric binder on the basis of epoxy-dian resin in the amount of 18-20 wp, while on the surface of the fibres of the roving base before it is impregnated a layer of organosilicon sizing with carbon nanotubes is preliminarily applied by treating the fibres with 1-2% solution of the organosilicon sinter in ethanol with carbon nanotubes in the amount of 0.001-0.005 wp of the carbon nanotubes and 0.1-0.2 wp of organosilicon coupling agent. The fibres of the roving base are treated with a solution by ultrasonic treatment of the solution. The method provides improved performance properties of composite materials.

EFFECT: produced composite material allows to produce high-strength composite products, in particular, in the manufacture of reinforcement, rods, and profiles with a high modulus of elasticity and tensile strength.
