NICOP - Trans-jacket fibre Bragg gratings for in-situ health monitoring of Defence platforms in harsh environments
Abstract
This project will investigate emergent techniques for femto-second laser inscription of fibre Bragggratings (FBGs) through the fibre coating to facilitate enhanced sensor performance for structuralhealth monitoring in harsh operational environments. The ultimate strength and fatigueperformance of these FBG sensors will be characterised and compared to currently available FBGsand draw-tower gratings (DTGs). This work has the support of ONRG Tokyo deputy director Dr.Ming-Jen Pan (Platform Design and Survivability) will include involvement from ONR-HQprogram officer Dr. Ignacio Perez (Code 33) through sponsored programs at the Naval Researchlaboratories (Dr. Geoff Cranch) and the University of Nebraska Lincoln (Professor Ming Han).The outcomes of this work will include; (1) t"he development of processes for volume assessmentof the mechanical and optical performance of trans-jacket FBG sensors, (2) the pro"vision ofstatistically significant reliability and durability data and comparative evaluation against currentstate-of-the art FBG sensors and (3) analysis on the potential suitability of this new class of FBGsensor for future implementation as an in-situ tool to inform structural asset management ofDefence platforms. It is expected that the outcomes of this fundamental research will be p"ublishedin the open literature. The outcomes of this work align with the Naval S&T focus areas ofAutonomy and Unmanned Systems, Pl""atform Design and Survivability (Vehicle Structures andmaterials, structural materials) and Power Projection and Integrated Defense" (Reduced platformlife-cycle costs).
