Syntactic foam, consisting of hollow glass microballoons and epoxy resin, has been used as the principle buoyancy materials in recently developed deep submersibles. So, the authers developed the syntactic foam of non sorting microballoons and standard resin from 1969 to 1972. The foams specific gravity is 0.63 and the collapse pressure is more than 1,200 kgf/cm^2. The present studies were aimed at exploring special means of achieving a lighter and high-strength foam for 6,000m submersible in near future. As the result, the effect of microballoon size and packing factor on foam performance, and the relation between foam collapst pressure and uniaxial compressive modulus of epoxy resin were confirmed. Furthermore, we have succeeded in development of the high-performance syntactic foam, the specific gravity is from 0.53 to 0.56 and the collapse pressure is approximately l,200 kgf/cm^2, the same as U.S. Navy developed in 1980.
