The aim of this Masters of Engineering (MEng) - Aerospace thesis was to investigate the durability of Piezoelectric Wafer Active Sensors (PWAS) for the health monitoring of composite structures. One significant challenge faced by the aviation industry is the cost and time associated with maintaining aircrafts, in particular, aging airliners. Structural Health Monitoring (SHM) is a possible approach to reduce the high cost of inspection and maintenance.

The performance of the simulation scheme has been compared with the commercial and laboratory samples in the world. Due to the deviation of all dosimeters with a flat energy response, in this paper, has been used an idea of one semi-conductor sensor to have the flat energy-response in the entire neutron energy range. Finally, by analyzing of the sensors data as arrays for the first time, we have reached a nearly flat and acceptable energy-response.
