The objective of this Phase I STTR program is to develop innovative lightweight (density < 1.17 g/cm3) polyureasiloxane hybrid coatings as multi-mechanism blast, fragmentation and environmental protective coatings for the Marine Corps Expeditionary Fighting Vehicle. NanoSonic will synergistically combine the impact resistance and mechanical durability of its existing hybrid polyureasiloxane copolymers with the hardness, flame resistance of reinforcing ceramic nanoparticles to afford novel protective coatings for mitigating blast, fragmentation threats. The proposed effort will build from NanoSonic’s existing hybrid polysiloxane coatings that have independently validated 1) V50 values greater than 4,000 ft/s when deposited on 3/8” A36 steel panels (MIL-STD-662F), 2) multiple shot protection to 0.50 cal rounds and 3) flame resistance (time to ignition > 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.
