CARBON/CARBON CARBON/CARBON COMPOSITESCOMPOSITES

C/C composites are lightweight, high-C/C composites are lightweight, high-strength composite materials capable strength composite materials capable of withstanding temperatures over of withstanding temperatures over 30003000°°C. C.

What are C/C Composites?

C/C composites use the strength C/C composites use the strength and modulus of carbon fibers to and modulus of carbon fibers to reinforce a carbon matrix to resist reinforce a carbon matrix to resist the rigors of extreme environments.the rigors of extreme environments.
