COMPARISON BETWEEN NUMERICAL SIMULATION AND EXPERIMENTAL RESULT OF RESIN FLOW IN RTM

The molding filling process is a very important phase in RTM. This paper studies the RTM process and its resin flow process. The governing equations of resin flow are built up. The boundary-fitted coordinate system and the finite difference method are employed for simulating the resin flow process. The successive resin flow front position and the pressure distribution at the final stage are obtained, and good agreement is found between the numerical simulation and experimental results as well as other investigations.
