Abstract

Active Fiber Composites (AFCs) are composed of uniaxially aligned piezoelectric fibers embedded in a polymer matrix. Two interdigital surface electrodes deliver the required driving voltage. A new concept for anisotropic matrix materials in AFCs has been successfully introduced. The matrix material is doped with ferromagnetic, electrically- conductive particles. The particles are locally aligned during AFC manufacturing by magnetic fields and create an electrically-conductive path between the electrodes and the surface of the piezofibers. The new method allows for more flexibility in the design and processing of AFCs and should lead to reduced driving voltages for AFCs. A manufacturing rig for magnetic particles AFCs (mpAFCs) has been designed and fabricated. A materials system has been optimized and processing methods for production of mpAFCs were developed. Several mpAFCs have been successfully manufactured and characterized. Actuation authority of mpAFCs was investigated and compared to standard AFCs.
