Abstract

The present invention is a method for real-time controlling a resin transfer molding process, which is used to control a filling pressure of a resin in a resin transfer molding (RTM) apparatus. In a pre-control RTM process, the current filling pressure, the current permeability and the wave front position at the current time point is input into a prediction-control model to acquire a predicted filling pressure at the next time point. The predicted filling pressure is used as the filling pressure to make the resin flow to the expected position of the wave front at the next time point, whereby to achieve stable quality of RTM products.
