Abstract: In this article, the fiber optic acoustic hydrophone made with a composite structure design. The structure is designed with different material layers and structural properties. The sensing plastic spool is outlined certain to existing harmonic frequency ranges at 0.2 to 2.5 KHz. In this research paper, the major pivot was to prototyped the mandrel which remained at a gap ranging from 20 to 200 meter underwater accompanied by varying constructional and material properties having non-identical friction coefficient. A design has much rapport with two fiber optic layers which wounded over center of length of mandrel. However the magnitude of sensitivity is determined to be -20.172dB for the applied static force of 0.2 Mega Pascal. Pre-managing of sensing composition is performed using Hyper Mesh model, inspection is performed in ABAQUS CAE software and conceptualization of results in Hyper View model appliance. On any occasion, the force is registered on the mandrel, phase variation in light together with path length of fiber change which measures sensitivity mathematically.
