Low density 6500 meter man-rated syntactic foam

The objective set forth in this SBIR Topic is for the development of a 6500 meter man- rated syntactic with a composite density of 30 +2/-1 PCF. The topic description maintains that the current state-of-the-art man rated foam has a minimum density of 35 PCF. However, in 2009 through mid 2010 Engineered Syntactic Systems, (ESS), successfully manufactured a 34 lb/ft3 syntactic capable of meeting the specification under a WHOI purchase order. Ten cubic feet of foam was delivered and successfully tested to the MIL-S-24154A standard by WHOI. ESS intends to build on the success of this development, its current syntactic foam manufacturing experience and expertise, and described processing innovations under consideration to attain the target 30 lb/ft3 6500 meter man-rated system.
