Popis:	In this work, temperature fields have been modeled during autoclave molding of VKU-46 carbon-fiber-reinforced plastic. It has been shown that a degree of conversion of 97.2–98.4% is achieved in the center of plate upon curing according to the chosen temperature–time mode, while the material is cured completely near the ends. In this case, the glass transition temperature of the material is in the range of 193.2–205.7°C upon preliminary heating. On the contrary, it decreases to 182.5–197.6°C at repeated heating due to the conformational change of macromolecules.
