POLYMER COMPOSITE BASED ON POLYESTERESTERKETONE AND CARBON FIBER AND A METHOD FOR ITS PRODUCTION Russian patent published in 2021 - IPC C08L71/00 C08L71/10 C08J5/06 C08K7/02 

FIELD: chemistry.

SUBSTANCE: present invention relates to polymer composite materials designed as super-constructive polymer materials, and to a method for their production. The polymer composite material contains polyesteresterketone as a polymer matrix containing 20 wt.% of the filler. The filler is a carbon fiber dressed with 4,4'-dihydroxybenzophenone. The method for the production of the polymer composite material includes pre-mixing of polyesteresterketone with the dressed carbon fiber, followed by extrusion of the resulting polymer mixture. Carbon fiber dressing involves applying a dressing component from a solution with a mass fraction of 4,4'-dihydroxybenzophenone of 0.6-1.08% in an organic solvent, followed by drying.

EFFECT: technical result of the present invention consists in increasing the destructive tension and elastic module under tension of the created polyesteretherketone carbon fiber composite by introducing a dressing composition that increases the wettability of the carbon fiber and increases the intermolecular interactions between the carbon fiber and the polyesteretherketone matrix.
