1. A method for fabricating a member in a resin-infusion-based casting process, in which at least one component forming the member is infused with a resin, the method comprising:
providing a mold, the at least one component, the resin, at least one measurement device and at least one sensing device, wherein the at least one sensing device has at least one property which changes measurably with temperature and/or when the at least one sensing device comes into contact with the resin;
attaching the at least one sensing device with a flexible substrate to an inner surface of the mold and/or to the at least one component;
arranging the at least one component inside the mold;
providing the resin to at least one inlet of the mold; and
wirelessly measuring and evaluating the at least one property of the at least one sensing device with the at least one measurement device for monitoring a temperature and/or a distribution of the resin in the mold and/or in the at least one component.
