Abstract

The development of damped structural materials is an area of current research with potential for high rewards. Resistively shunted piezoceramic fibers used as reinforcement in a structural composite mate-rial offer the potential to significantly increase vibration damping capability. Available data indicate the predictable nature of this electroelastic damping mechanism, an important concern in design. This arti-cle addresses the current status of an effort to develop damped composites using resistively shunted pie-zoceramic fibers, including modeling aspects, performance limits, design guidelines, and fabrication issues. Initial design guidelines take the form of a modified modal strain energy method. With longitudi-nally poled fibers, peak damping loss factors of 12% are attainable in principle, even at relatively low (30%) piezoceramic fiber volume fractions. Some 30-μm diameter piezoelectric fibers have been pro-duced using a solgel method, and details of poling and shunting are under investigation.
