A model of temperature field and phase change in the carbon fiber preform was established based on heat and mass transfer of gas and fluid phases flow
heat conduction between the preform and kerosene
and heat and mass transfer in the carbon fiber perform. A numerical investigation on preparation at the vaporization temperature 453.15 K for the preform with a diameter of 70 mm using induction heating was performed. The change of the temperature field with time in the preform was obtained. The temperature distribution at different time
the variation of radical temperature with time
and vapor rates along the radical direction in the phase change process were indicated. The computing results are in agreement with the data of the actual power input of electric heating.
