Abstract: The modern RTM process is actually a non-isothermal process due to the high speed of the filling mold and the short curing period. By analyzing the process and investigating related problems，a mathematical model was founded considering energy conservation equation and curing equation by using CV/FEM and upwind scheme. The differential equations were also discretized and integrated. The control equations fitting for numerical simulation are produced and the code is developed，and the calculation results are in agreement with those of the correlative literature.
