Abstract

The research tried to examine the viability of the embedment of optical fiber sensors in Additively built components, packaging the sensors within the components, and characterizing the sensors for sensing a specified measurement. Optical fiber sensors are popular due to their small size, resilience against electromagnetic radiation, and reliability in potentially dangerous conditions. Embedding fibers inside a product allows for the monitoring of critical areas, allowing for preemptive action in the case of a breakdown. Coupons of Inconel 718 were made using laser powder-bed fusion (LPBF), with the fabrication settings tuned to determine whether such a development was possible. After the FBG sensors were inserted in the channel, thermal epoxy was injected to seal the package. After the sample specimen was created, they were put through some tests like fatigue and thermal tests to determine their properties. This was done so that designers in the future would have a road map to follow when creating such a component, and so that we could learn whether the design was viable in general.
