Carbon-based materials are widely used in aerospace industry due to their strength, heat shielding properties, and a number of other specific characteristics [1]. To trace the radiation damage influence on the erosion regularities the sputtering yields Y of highly-oriented pyrolytic graphite (HOPG), polycrystalline graphites and one-dimensional composite material under high-fluence (10 18-10 19 ion/cm 2) 30 keV N 2 + and Ar + ions at the incidence angles from θ = 0 (normal incidence) to θ = 80 o , developed morphology and crystalline phase state from low temperatures (T ~ −180 o C)
