A Thermal Balancing Analysis of Composites Reinforced by Different Shape Buckypaper

摘要

The software FLUENT was used to analysis the thermal balance of composites reinforced by different shape buckypaper during the heating process. The research shows that the electrothermal energy is mainly used to increase the temperature of the insulator and the heating plate itself at the initial stage of heating. Because the mass and heat capacity of the insulators are both greater than that of the heating plates, the insulators absorb more heat than the heating sheets. The heating rate of insulators and heating sheets slows down as time increases, which result in the decrease of heat absorption. The increase of external surface temperature makes convection heat dissipation increase, so the proportion of convection heat dissipation increases, and the endothermic ratio of material decreases.
