POLYMER COMPOSITE BASED ON CARBON FIBER-REINFORCED POLYETHERETHERKETONE AND METHOD FOR ITS PRODUCTION Russian patent published in 2021 - IPC C08L61/02 D06M13/133 C08J5/06 B32B5/28 

FIELD: polymers.

SUBSTANCE: invention relates to polymer composite materials intended as superstructure polymer materials, and a method for their production. A polymer composite based on polyetheretherketone reinforced with finished carbon fiber is proposed, in which a polyetheretherketone containing 20 wt% of a filler is used as a polymer matrix, and a carbon fiber, finished with dihalogenated diaryl ketone - 4,4'-dichlorodiphenyl ketone, consisting of components, in wt%: carbon fiber (96-98), 4,4' dichlorodiphenyl ketone (2-4). A method for producing the specified composite is also proposed.

EFFECT: technical result is increase in impact strength, breaking tensile stress and elongation of the created polyetheretherketone carbon fiber composite due to the introduction of a finishing dihalogenatedarylketone, which increases the wettability of carbon fiber and increases intermolecular interactions between the filler and the polyetheretherketone matrix.
