摘要
Provided by the present invention is a method to measure the curing behavior, flow, and impregnation degree of resin when producing a resin composite by VARTM. The method provided by the present invention comprises the following steps of: having a structure stacked in a vertical direction and arranging a plurality of conductive fiber sheets in a woven form; including a plurality of electrode pairs electrically connected to the front end and rear end of each of the conductive fiber sheets, and connecting a resistance measurement module for measuring a resistance change of each of the conductive fiber sheets by using the electrode pairs; sealing the conductive fiber sheets with a sealing member; supplying non-conductive resin into the sealing member and flowing the same from the front end of the conductive fiber sheets toward the rear end of the conductive fiber sheets for the conductive fiber sheets to be impregnated with the non-conductive resin; measuring resistance between the electrode pairs by using the resistance measurement module when the conductive fiber sheets start to be impregnated in the non-conductive resin. The present invention reduces the degradation of mechanical features generated when inserting a sensor and increases a monitoring effect of a manufacturing process since no separate measurement sensor is required by using the conductive fiber sheets as a sensor.
