FIELD: chemistry.
SUBSTANCE: composite material contains carbon fibers and matrix resin. The matrix resin comprises (a) a resin component comprising 20 wt % to 25 wt % of diglycidyl ether of bisphenol-F and 20 wt % to 25 wt % of triglycidyl-p-aminophenol, (b) thermoplastic particles comprising, at least, 95 wt % of polyamide, which is a polymeric condensation product of 1.10-decanodicarboxylic acid and an amine component, for example a methyl derivative of bis (4-aminocyclohexyl) methane, (d) simple polyether sulfone, (e) diaminodisulfone as a curing agent.
EFFECT: invention makes it possible to produce a pre-impregnated composite material having high compressive strength under heating and humidity conditions, as well as high allowable damage and interlayer fracture toughness.
