POLYPHENYLENE SULPHIDE COMPOSITE MATERIALS WITH CARBON FIBRES AND METHOD FOR PRODUCTION THEREOF Russian patent published in 2022 - IPC C08L81/04 C08J5/06 C08K7/02 

FIELD: composite materials.

SUBSTANCE: invention relates to polyphenylene sulphide composite materials with carbon fibres intended as structural polymer materials, and to a method for production thereof. The composite material includes polyphenylene sulphide and carbon fibres coated with an organic finishing agent, wherein a polyhydroxy ether based on 1-chloro-2,3-epoxypropane and 4,4'-dioxyphenylpropane in a volatile organic solvent is used as such agent. The amount of the applying substance relative to the carbon fibre is 1 to 4 wt.%. The amount of finished carbon fibre in the composite material is 20 wt.%.

EFFECT: resulting composite materials exhibit improved physical and mechanical and rheological properties due to the introduction of a finishing agent enhancing the wettability of the filler and increasing the boundary interactions between the carbon fibre and the polyphenylene sulphide matrix.
