High Temperature Turbine Blades 


Pacoima, CA 

Net-shape fiber-reinforced metal matrix composite turbine blades, produced by a unique chemical vapor infiltration (CVI) process
Ceramic Composite Thrust Chamber with Metal Flange Attachment
Ceramic Composite Thrust Chamber with
Metal Flange Attachment
    • Evaluated continuous refractory fibers as strengthening reinforcements for niobium metal matrix
    • Developed controllable, repeatable process for infiltrating niobium metal matrix into fiber preforms
    • Ultimately spun off technology into fabrication of load- bearing, hermetically sealed ceramic-to-metal joints for use in high temperature propulsion systems
    • Ceramic-to-metal joints fabricated for Missile Defense Agency/Army Theater High Altitude Air Defense System (THAADS), with $750K in sales to propulsion contractor (Rocketdyne)
    • Ceramic-to-metal joints fabricated for DOE/Navy submarine nuclear reactor program, with $500K in sales to industry contractor (GE/Knolls Atomic Power Laboratory)
    • The same Niobium joint technology is being used under DOE Phase II development to attach tungsten-based heat exchangers via conventional welding methods
    • Other applications being explored are aerospace propulsion and power systems, including intercept vehicles for missile defense, nuclear submarine reactors, advanced aircraft turbine engines and liquid rocket turbomachinery
