| Research Abstract |
Life cycle monitoring of aircraft CFRP structures was established using optical fiber sensing which measures strain and temperature throughout the life including curing process, assembly and operation. Structural health diagnosis can be performed based on the accumulated strain history and material strength data. A new methodology was proposed for quality assurance and maintenance of complex CFRP structures based on the optical fiber sensor responses, and successfully applied to bolted joints, curved corner parts, think plates and pipes.
