Chemical Vapor Infiltration Products

For Aerospace Structures & Rocket Propulsion

Carbon/Silicon Carbide material with T300 Carbon fiber reinforcement offers high temperature strength and toughness for structural and heat shield components. Novoltex/Silicon Carbide components are used for a variety of rocket propulsion applications; primarily for hot gas valve and exhaust nozzles in divert and attitude control systems. The table below identifies properties for these applications although variations are available to meet other solutions.
