Investigation of Structural Problems with Filament Wound Deep Submersibles

摘要

This program investigated some of the structural problems originating in the application of the filamentwound composite to the hulls of deep-diving vehicles. Small scale models were designed, fabricated and tested under static and cyclic external pressure. A design collapse pressure of 13,333 psi, and 10,000 cycles to one-half of this pressure were program objectives. Problems of major concern were closures, closure attachment, closure and cylinder penetrations, transverse cylinder joints, and positive frame attachments.
