MASSIVE GLASS AS A NAVAL-STRUCTURAL MATERIAL,
  Publication NMAB262, National Academy of Sciences-National Academy of Engineering, Washington, D.C., April 1970,108 pages.

Massive glass has potential as a structural material for a variety of high efficiency, deep ocean applications. However, neither the existing data on massive glass nor current industrial production capability are adequate for the task. This is especially true in producing a man-rated glass pressure hull by a target date of 1980.

The application of glass as a structural material for deep submergence has been reviewed and evaluated in this report. Specific areas of glass technology requiring research, development, testing and evaluation effort are described. A structural design scale-up program using models and full-size pressure hulls is suggested. Concurrent materials studies, design evaluation programs, and production development are recommended.
