Since a fiber reinforced plastic (FRP) structure is complicated in the adoption of integral molding, VaRTM (Vacuum assisted Resin Transfer Molding) by which a complicated structure is made easily is in widespread use. But local molding fault such as dryspot is liable to occur in VaRTM due to complicated structure. To solve this problem, the impregnated area for the entire composite structure has to be measured. In the present study, we propose a patch-type flexible interdigital electrode based on impedance measurements. The flow of resin in VaRTM using the device is measured. Moreover, dielectric heating with high frequency changes the viscosity of resin. As a result, we confirmed the effectiveness of measuring the impregnated area using proposed device and the avoidance of dryspot occurrence by electric heating.
