Ultra-High Temperature Dynamic Seals for Extreme Environments

To meet the need for greater duration, higher altitudes, and longer time of flight, solid propulsion systems will require greater impulse and thrust, primarily achieved through the increase of solid propellant burn temperatures. There is a need for new extreme environment materials for solid rocket motors. To address this need, Luna Labs has designed, tailored, and developed an ultra-high temperature performance polymer composite with a demonstrated glass transition temperature greater than 900 °F. The material has demonstrated thermal, mechanical, and sealing properties to meet the MDA’s need for new polymeric materials. In Phase II, Luna Labs will improve mechanical properties for better sealing and compressibility as well as optimize processing. Dynamic sealing will be demonstrated.
