摘要
FIELD: chemistry.;SUBSTANCE: invention relates to composite materials, containing cyanate ester resin as a polymer matrix. The said highly-strong composites are suitable for application as basic constructions in aviation and in other load-bearing applications. Matrix resins constitute 50-80 wt % of a cyanate ester resin component. The matrix resin composition also contains 10-40 wt % of a thermoplastic mixture, consisting of poly(ether)imide, polyamidimide and 1-15 wt % of a fire retardant, with the said fire retardant containing phosphorus-containing cyanate ester resin. The composition can additionally contain from 1 to 10 wt % of a curing agent.;EFFECT: composites possess an improved impact strength, have low characteristics of heat release and a short time of self-extinguishing.;20 cl, 6 dwg, 4 ex
