Implosion of Advanced Composite Structures within Complex Underwater Environments

Abstract

Implosion studies of composite structures in various environments are carried out using state of the art facilities. In sandwich composite structures, the collapse pressure is higher than an unbonded sandwich structure. In fully confined, limited energy environments, partial implosion and complete implosion phenomena are noted. Another important outcome is that a small decrease in inter-tube standoff distance, implosion of one composite cylinder can cause the buckling of a nearby composite shell. Also, marine weathering was observed to degrade material and structural properties. Additionally, decreasing radius-to-thickness ratio of shells causes a transition from symmetric to catastrophic collapse.
