Complex Underwater Implosion Phenomena and Mitigation of Implosion and Implosion Pulses in Marine Compostie Structures
Abstract
The proposed experimental study will investigate and develop strategies to mitigate implosions in underwater composite implodable volumes. These strategies will be to develop and analyze structures with stiffeners, pressure-mitigating filler materials, and hybrid fiber layup configuration. Additionally, implosion near surrounding structures also referred to as sympathetic implosions, will be investigated. The experiments will be performed using state of the art underwater research facilities at the University of Rhode Island (URI). These facilities were established under the Defense University Instrumentation Program funding granted by the Office of Naval Research. Within the Navy, the phenomenon of implosion has become a topic of interest for mitigating catastrophic failures in various applications. One of the main concerns is ship safety and the effect a near field implosion can have on its integrity. With the recent advancements in structural composite materials for marine applications, it is essential to understand the effects of composite materials collapse in complex submarine environments. Recent work by URI in this area has contributed to the overall understanding of implosion pressure pulses interaction with large metallic plates and sympathetic implosions of carbon composite shells in proximity to each other. Work has also been carried out at URI recently to explore the effects of fillers and stiffeners on metallic shells implosion. This proposed work seeks to advance the knowledge gained from such studies investigating complex problems involving composite shells implosion. The implosion of carbon-fiber composite and hybrid composite materials will be used to understand differences in secondary structures stability and response. The influence of polymeric coatings on such responses will also be pursued. Additionally, the effects of filler materials and stiffeners will be investigated to mitigate implosion pressure pulses from composite shells.
