Carbon/Carbon (C/C) is a lightweight, high-strength composite material capable of withstanding temperatures over 3000°C in many environments.  Carbon/Carbon Composites use the strength and modulus of carbon fibers to reinforce a carbon matrix to resist the rigors of extreme environments.  Using FMI^® specialty weaving techniques, composite structures can be tailored to meet varied physical and thermal requirements through weaving architecture design.

FMI woven reinforcements are impregnated with resin or pitch and carbonized to yield finished, fully dense composites using well controlled temperature and pressure processes (up to 15000 psi).

At one-tenth the density, C/C offers a high performance, cost effective alternative to refractory metals.  Aerospace components commonly fabricated from C/C include rocket motor nozzle throats and exit cones, nosetips/leading edges and thermal protection systems.  Reliable performance is the most critical requirement of these components. FMI C/C Composites have demonstrated reliability and reduced systems costs, especially when multiple components in an assembly can be replaced with a one-piece C/C design.

Commercial applications of Carbon/Carbon materials include furnace fixturing, heatshields, load plates, heating elements and X-ray targets.
