The objective of this Phase I STTR program is to develop innovative lightweight (density 280 seconds at 50 kW/m2, average heat release rates of 38 kW/m2). To provide an initial proof-of-concept, NanoSonic has recently synthesized low modulus (E = 5 MPa) polyurea coatings that have tensile resiliency beyond 1000 % elongation, service temperatures from -60 to 300 C and V50 values 23 % greater than currently investigate blast resistant polyurea coatings (MIL-STD-662F). In addition, NanoSonic has received strong interest from General Dynamics, Northrop Grumman and Lockheed Martin for potential integration within numerous DoD vehicle platforms.
