Research of Smart Materials and Structures at NUAA
The research activities of the Aeronautic Science Key Lab for Smart Materials and Structures,Nanjing University of Aeronautics and Astronautics are introduced.The research fields include structural health monitoring,structural vibration reduction and noise suppression,adaptive wing and smart rotor,sensor and actuation technology,functional materials and devices,and system integration and measurement technology.Three fields of research are introduced in detail.The first field is the structural health monitoring(SHM).Research subjects includes hybrid structural health monitoring using FBG sensors and piezoelectric sensors,wireless sensor network,multi-agent based distributed SHM technology,and braided composites with embedded optic fibers.The second field introduced is development of high-performance piezoelectric materials using a hybrid sintering process consisting of microwave heating and hot-press.This approach is applied to the fabrication of PZT and PNN-PZT materials and their properties were improved significantly.The third field introduced is the development of high-performance piezoelectric devices,including functionally graded piezoelectric actuators and piezoelectric fibers.The functionally graded piezoelectric actuators are fabricated by gradually changing the piezoelectric and dielectric properties of the materials in the thickness direction of the actuator.
