In order to clarify the polymerization mode of a carbon fiber cylinder, mathematical modeling of the process of heating a composite structure (cylinder) by infrared radiation using the finite difference method was carried out. Using mathematical modeling, it was found that under given polymerization conditions, when exposed to infrared heating, the carbon fiber cylinder will reach a cured state within 120 minutes. The calculation data are confirmed by an analysis of the degree of polymerization of a carbon fiber fragment cut from a cylinder, cured by infrared heating. The degree of polymerization of carbon fiber using infrared radiation during curing is 95—96 %.
