Smart Coating Sensor Applied in Crack Detection for Aircraft

Abstract:

Monitoring fatigue cracking of large engineering structures is a costly and time-intensive process. The authors present a low-cost smart coating sensor (SCS) consisted of driving layer, sensing layer and protective layer typically that can detect crack initiation and growth. The results show that the smart coating sensor can detect cracks above 300μm, corresponding to the increment of the sensing layer’s electric resistance at the level of 0.05Ω. Therefore, the development of SCS is of importance significance in the substitution of an existed inspection that requires substantial disassembly and surface preparation, and, thus, can find numerous applications in difficult-to-access locations on aircrafts.
