Macrofiber piezoelectric composites are thin rectangular patches made of polyimide film, epoxy and a single layer of rectangular lead zirconium titanate fibers and are commercially available. As a basis for this consideration, the useful life of the MFC is being characterized to determine the effect of loading condition on the performance of the material as it is fatigued by cyclical piezoelectric excitation. The test specimen consists of the MFC laminated to a cantilevered stainless steel beam using epoxy and is actuated at the first resonant frequency of the beam laminate by the cyclic application of 1000 volts. Strain and beam tip displacement measurements are used as a basis for determining the performance of the MFC as it is cyclically actuated under varying beam thicknesses.
