Implosion of Advanced Composite Structures within Complex Underwater Environments
Abstract
SHORT WORK STATEMENT:- The behavior and performance of hybrid carbon-glass composites will be investigated regarding natural and shock initiated implosions. - Specimens will be created with different non-woven layout patterns and different carbon-glass ratios to optimize the performance of hybrid implodable structures regarding energy release. - Shock initiated experiments will use a detonator at various stand-off distances and different initiation pressure such that the experiments are performed at different shock strengths.- The generation of pressure waves from a composite implosion and the interaction of the pressure waves with the confining tube walls will be investigated for a fully confined environment (where hydrostatic pressure is limited) and a semi-confined environment (where hydrostatic pressure is unlimited and leads to hammer waves).- Multiple studies will be performed to evaluate how implosion can affect and damage adjacent structures.- Implosion of carbon composite tubes will be performed with proximity to a plate in order to analyze the collapse behavior while constrained to flow restrictions.- Sympathetic implosion of two or more composite structures will be analyzed in order to analyze how an implodable body can interact with, and possibly damage, other implodable structures.- Carbon/epoxy tubes will be exposed to seawater and their implosion performance will be evaluated.
