| Summary | A new type of multifunctional composite material has been established by integrating parallel arrays of tiny piezoelectric fibers with interdigital electrodes into polymer matrices. This follows the approach of structural conformity to maintain the mechanical properties of the composite materials. The access to highly integrated materials consisting of at least four solid phases is based on the combination of fiber technology, electrodizing, composite fabrication and adaptive control. The sensing as well as the actuating properties of the resulting materials are evident. This offers a wide range of possible applications like active and passive vibration damping, health monitoring, structural control and impact detection. |
