Development of Resin Transfer Molding Process Numerical Simulation

This paper presents a summary on studies of factors which influence the quality of finished parts based on permeability of fibrous preform, voids or dry spots and residual stress. According to governing equations used in the simulation of RTM process, advantages and disadvantages of several different numerical methods are briefly introduced. From the research trends at home and abroad, future development of the RTM process numerical simulation is also prospected.
