ABSTRACT:
The present invention is directed to the formation of pressure resistant buoyancy structures with a given buoyancy efficiency at smaller sizes. The invention involves embedding into syntactic foam metallic spheres which preferably are substantially hollow and comprise high strength, high performance, light weight metal alloys which can be precision forged. The weight per unit space of the metallic spheres is less than that of the syntactic foam. As a result, the metallic spheres can decrease the size of the structure required to achieve a desired buoyancy efficiency.
