MEASUREMENT DEVICE AND METHOD FOR MEASURING THE TENSION OF CARON FIBER TOWS

Abstract:

A measurement device for simultaneously measuring the tension in a plurality of fiber tows mounted within a deposition head of a fiber placement robot. The measurement device includes a plurality of load cells and a plurality of connectors. The connectors are connected to the load cells. The connectors are adapted to be connected to a respective one of the plurality of fiber tows. Movement of the fiber placement robot in relation to the measurement device generates a plurality of measured tension readings, each being associated with a respective tension in each of the plurality of fiber tows. The measurement device also includes at least one controller. The controller receives the plurality of measured tension readings, compares each of the plurality of measured tension readings to a predetermined tension, and outputs a deviation signal indicative of whether one or more of the plurality of tension readings deviates from the predetermined tension.
