Commercial Carbon Composites (C3® )
Commercial Carbon Composites is a high strength two-directional fiber reinforced composite
material designed to meet stringent structural and high temperature applications. Weave
construction results in excellent through-the-thickness thermal properties and a superior
insulation material. C3 incorporates all the inherent properties
of graphite, with a lower density, superior mechanical properties and a higher resistance to fracture.

| Carbon/Carbon Composite - Barrier Grade |
| is a low-cost composite designed to be used as a thermal shield as
well as a facing material on FMI's FiberForm® / felt
insulation materials to provide an erosion resistant impervious surface in a rapid gas
quenching environment and protection from physical damage and chemical attack. C3 barrier
grade is available in 1/2 mm up to 2mm plates, channels and angles. |
