REPORT ON THE DEVELOPMENT OF BUOYANCY MATERIALS FOR DEEP SUBMERGENCE

摘要

The Laboratory is conducting an R&D program to develop buoyancy materials for deep submergence applications. In reference (a) the Laboratory informed the Bureau that work was underway to determine the effects of con tenuous hydrostatic exposure for 10C0 hours at 10,000 psi on Laboratory developed syntactic foam formulations MLB-1, MLB-2 and MLB-3 and several cominaercial materials. On the occasion of reference (b), a representative of the' Bureau requested that these candidate materials also be subjected to 1000 cycles of hydrostatic pressure varying from atmospheric pressure to 10,000 psi.
