(NURP) Effects of Combined Depth Pressure and Long Term Seawater Immersion on Structural Integrity of Composite Vehicles
Abstract
ABSTRACT:The proposed experimental-numerical study will investigate the effects of combined extreme hydrostatic depth pressure and long term seawater submergence on the integrity and performance of composite materials and vehicles/payloads, specifically, the degrading effects of the severe environment. The emphasis will be on understanding the fundamental physical mechanisms of seawater ingression when combined with the driving force of deep ocean pressures, as well as identifying the adverse effects on the structural integrity of a naval payload when subjected to this combined loading environment. The focus of the work will be on performing experiments using state of the art facilities that have been developed in recent years with ONR / Navy funding to support accelerated aging studies and structural evaluations under severe loading conditions (hydrostatic, shock, implosion).The successful completion of this project will result in an in depth understanding of the performance of navy relevant composite materials and vehicles when exposed to seawater at extreme depths for prolonged periods of time and dynamic loadings. Furthermore, the study will give insight into the damage imparted on a larger vessel due to implosion of a nearby structure. An initial attempt will also be made to explore the physics of the underwater explosion of a composite wrapped pressure vessel.
