Embedding Intelligence for RTM Process Monitoring and Control
A technique to control the resin flow front in closed and open mould is described. The technique consists in embedding linear capacitive sensors to provide the position of the moving flow front. The embedded capacitor is made with two parallel wires while the resin, between the wires, acts as a moving dielectric which changes the capacitance values. Therefore the position of the resin is obtained from the measured capacitance variation. In order to validate the proposed methodology the sensor has been characterized and the obtained characteristic curve showed a quasi-linear trend. The shape of the resin front could be modified, if necessary, acting locally with controlled injectors.
