The simulation of resin flow during the resin transfer molding (RTM) process throughmultilayered textile fabric of known permeability and porosity has been attempted in thisstudy. A simple three-dimensional computational fluid dynamics (CFD) simulation modelhas been developed and the results of the simulation are compared with the experimentalRTM resin flow through multilayer interlocked woven structures. A multiphase simulationmodel is observed to reasonably predict the time for RTM mold filling. Fabric structuralinfluence in terms of an Interlacement Index (I) has significant influence on the resin flowbehaviour of the multilayered preform. A higher I of the preform means a longer time to fillthe mold in both the experimental and simulated results. Images of the simulated flow fronthas been compared with the experimental results and it is observed that not only the moldfilling time, but also the area of resin flow in the multilayer perform, is influenced by afabric structural factor, I.
