This study uses Fluent software to simulate the temperature distribution of the forming mold

analyzes the reason of the temperature distribution and uses variance as a standard to evaluate temperature uniformity. According to the characteristic that the thermal resistance is proportional to the material thickness

we improve the uniformity of temperature by increasing the thickness of high temperature area and reducing the thickness of low temperature area. The simulation result shows that ladder type plane mold and trapezoid plane mold can make the temperature distribution of the contact plane more uniform

which has great significance for improving the quality of the composite material components.
