Chemical Vapor Composite (CVC™) SiC for HAN Propulsion Systems

Trex will develop rocket motor components suitable for liquid HAN monopropellant propulsion systems utilizing its patented CVC SiC™ process. CVC SiC enables production of high quality SiC capable of handling extreme temperatures up to 3700oF, well within the requirement for the HAN propellant. Furthermore, near net shape fabrication of rocket motor components, such as nozzles, flame liners and pintles is possible via CVC™. Finally, addition of solid particles and chopped fibers has been demonstrated, which yield stress-free, robust composite SiC materials required for the extreme pressure and thermal loads in the intended application. The proposed Phase 1 will produce prototype, near net shape CVC SiC™ fiber-reinforced composites, thereby demonstrating a cost-effective manufacturing process for these high temperature components.
