In this work a numerical simulation of the Vacuum Enhanced Resin Infusion Technology (VERITy) process is carried out to predict the effect of lowering the infusion pressure on the compaction behaviour of the preform. Two infusion schemes with varying pressure differentials are selected. 1-d rectilinear line infusion is selected, so as to find the per KPa thickness variation in the two infusion schemes. The fill time required for the resin to saturate the preform is also calculated. A substantial saving in the time required for the infusion to be complete and the flow front to reach the vent is reported. These simulation results are important in deciding the length, cure time, resin system and preform system with differential pressure infusion scheme in the manufacturing of polymer composites. ©SACAM 2012.
