- Аннотация: Carbonization of carbon fabric reinforced plastics (CFRPs) with phthalonitrile matrices at 1000°C was investigated. Four different carbonization modes were tested. It was explored, that a mode with step heat rate is most beneficial. Two different phthalonitrile resins were investigated. Elemental analysis of final carbon-carbon composite (C/C) matrix was carried out and the results showed up to 88.5 mass% carbon presence. Final C/C density reached 1.5991 after only one cycle of impregnation-carbonization. Final porosity of samples reached 9.2%. These results allow to consider phthalonitriles as a prospective carbon precursor for C/Cs manufacturing. Mechanical testing of the C/C samples was performed (Compressive strength P = 72.2MPa, E = 11.8 GPa). Tribological data was received (coefficient of friction = 0.31, wear rate = 30 µ/min). Thermal analysis was carried out (χ = 72.94 W/m*K, α = 85.8 cm2/s).
