Composite Regenerator for Stirling Engine  

Energy Science Laboratories, Inc. 

San Diego, CA

    A process for carbon fiber flocking on a carbon substrate to produce high radial and low axial thermal conductivity at high temperatures (1000oC)
Example of Flocked Carbon Fiber
Example of Flocked Carbon Fiber
    • Development of a carbon-carbon composite matrix Stirling engine regenerator providing high temperature capability and high radial, low axial conduction
    • Developed a carbon fiber flocking process to fabricate the composite matrix regenerator
    • Sales of $2.4M, half of the sales were generated by carbon fiber flocking
    • Expansion of manufacturing facility by over 40% and increase in staffing by 33%
    • High conductance thermal interface gaskets for use in aerospace thermal management and electronics packaging
    • Carbon-carbon velvet materials for absorption of radiation currently being sold to a diverse customer base
    • Compliant heat transfer interface and composite phase change material for advanced refrigerators/freezers for Space Station and Space Shuttle
    • Black surfaces for stray light suppression in spacecraft instruments
    • Cathodes for high power microwave sources are currently being sold to DOD
