Enhanced Composites Integrity Through Structural Health Monitoring

Enhanced Composites Integrity Through Structural Health Monitoring

This paper discusses the topic of how the integrity of safety-critical structural composites can be enhanced by the use of structural health monitoring (SHM) techniques. The paper starts with a presentation of how the certification of flight-critical composite structures can be achieved within the framework of civil aviation safety authority requirements. Typical composites damage mechanisms, w...

Structural Health Monitoring using Carbon Nanotube (CNT) Enhanced Composites

Carbon nanotubes (CNTs) are being investigated as a means for large-scale inspection of composite structures. Several studies have shown that CNTs possess exceptional mechanical stiffness and strength, as well as excellent electrical conductivity and piezoresistivity. Thus, it has been proposed that CNTs could be used not only to reinforce composite structures for improved impact and delaminati...

Airborne Transducer Integrity under Operational Environment for Structural Health Monitoring

This paper investigates the robustness of permanently mounted transducers used in airborne structural health monitoring systems, when exposed to the operational environment. Typical airliners operate in a range of conditions, hence, structural health monitoring (SHM) transducer robustness and integrity must be demonstrated for these environments. A set of extreme temperature, altitude and vibra...
