Light Weight High Performance Syntactic Foam

During this Phase I program, we will develop a syntactic foam or similar material with less than 20 pounds per cubic foot density and greater than 200 ksi compressive modulus, which can be used to provide positive buoyancy to submarines by filling void spaces. Our objective will be achieved by combining low density microsphere fillers and short fiber reinforcements within a high-strength polymer matrix. These syntactic foams will be tested for density, compressive modulus and strength, and water absorption. Tests will also be conducted after thermal cycling, controlled humidity exposure, and accelerated aging. At the end of Phase I, we will provide a detailed Phase II plan, schedule and cost estimate.
