Embodiments of a missile, an airframe and a structure comprising piezoelectric fibers and a method for active structural response control are generally described herein. In some embodiments, a housing structure includes a composite material containing a plurality of piezoelectric fibers adapted to generate an electrical signal in response to a deformation in the structure and to deform the structure to provide low frequency stiffness and strength performance while attenuating high frequency vibrations.

What is claimed is: 1. A missile comprising:a missile airframe;a guidance system for controlling a flight path of the missile;a first housing for housing the guidance system, the housing containing a plurality of piezoelectric fibers adapted to generate a sensor signal in response to a deformation in the housing and to deform the housing in response to an excitation signal applied thereto;a control circuit to generate the excitation signal adapted to tune a structural response of the housing in response to frequency components associated with the deformation of the structure, and to apply the excitation signal to the fibers; anda mounting structure for mounting the first housing to the missile airframe.
