A procedure is proposed for obtaining components of the in-plane permeability from VARTM(Vacuum Assisted Resin Transfer Molding) experiment on flow front position and time. This experiment was designed as unidirectional flow. Measuring the three direction permeability, the in-plane permeability can be characterized as elliptic pattern. To verify this experiment result, the experiment with hemispherical specimen and the simulation which was performed in numerical flow analysis software (PAM-RTM) were compared.
