A kinetic model of the formation of a pyrocarbon layer on the surface of filaments of carbonized PAN fiber is proposed. The resulting kinetic model is confirmed by experimental data. Models for the formation of a pyrocarbon layer and an increasing of thickness of a pyrocarbon layer on a bundle of carbon fiber filaments after a long cycle of CVD are predicted.
