What Is Carbon Carbon Composite?
Carbon carbon composite, also called CFC, is a carbon fiber reinforced carbon material used in high-temperature applications.
Basic Meaning
Carbon carbon composite is often abbreviated as CFC. It is used where a carbon-based structural material is needed in demanding high-temperature environments.
Where It Is Used
Common application discussions include heat treatment furnace parts, semiconductor-related process parts and solar photovoltaic high-temperature components.
Technical Specifications
The carbon carbon composite page lists RG-CC values including density, electrical resistivity, strength, thermal expansion and thermal conductivity. Directional values are retained where available because orientation can matter when reviewing a component.
Practical Buying Checklist
- Define the function and load direction of the component.
- Provide a drawing with dimensions, tolerances and quantity.
- Review density, strength, electrical and thermal properties.
- State machining, inspection, packaging and delivery requirements.
What to Discuss With a Supplier
For machined CFC parts, a drawing is more useful than a general request for plate material. Identify critical dimensions, orientation, holes, edges and any inspection points that should appear in the quotation.
Verify Before a Volume Order
Confirm the material grade and drawing revision before production. For a new component, evaluate a sample or first article in the intended high-temperature process before approving repeat volume.
