Abstract:Compounds based on the synthesized polyimides and organosilicon resins were developed. The compatibility of organosilicon resins with polyimide binders was studied by electron microscopy. The possibility of preparing fibrous composite materials, carbon-reinforced plastics, using such polyimide-organosilicon binders was demonstrated. The viscoelastic and strength properties of the materials obtained were studied. The optimum binder composition, ensuring 90% preservation of the elastic modulus and 70% preservation of strength of the carbon-reinforced plastic relative to the initial values after keeping in air for 50 h at 350°C, was chosen.
