In recent years, Vacuum assisted Resin Transfer Molding (VaRTM) process is attracting attention so that FRP products can be obtained at low cost than the autoclave. VaRTM process is a method which thermosetting resin is impregnated to fiber base material by vacuum pressure. Many types of equipment have been used for VaRTM process. It has been reported that arrangement of subsidiary material affects the impregnation rate. Therefore, permeability which indicated to resin impregnation properties is the key parameter in VaRTM process. In this study, effect of measurement conditions on permeability of Non crimp fabric (NCF) was investigated. Permeability was calculated by measuring the impregnation behavior of epoxy resin into NCF and using Darcy's law. This study suggested that the resin supply position and the inner diameter of the hose are influential factors of permeability.
