Active Fiber Composites (AFC) can be used as sensor or actuator and they can combine both functions in a single component. AFC are manufactured similar to traditional composites and can be built into composite structures to serve as both active and structural components. This paper presents the mechanical and sensor properties of AFC developed at Empa. The experimental determination of elastic material properties is described. The results are compared to Rule of Mixture (ROM) estimates and found to be in good agreement. Experiments for determining the sensor charge density response versus biaxial strain are presented and a transverse sensitivity of 6% is found. The results and experimental difficulties inherent to AFC testing are also discussed.
