CFC is for a high-strength composite material consisting of a carbon or graphite matrix with carbon fiber reinforcement. this combination of carbon or graphite with carbon fibers unites the many and varied favourable material properties of fiber composites with those of electrographite.

Heat resistance under protective gas up to temperatures in excess of 2000℃
High specific strength and rigidity
Low density and open porosity
Low thermal expansion
Extremely high resistance to thermal shock
Electrical conductivity
Anisotropy : in materials with aligned carbon fibers the flexural and tensile strength and also the electrical and thermal conductivity have different values parallel to the fiber from those perpendicular to the fiber or layer
Excellent resistance to alternating loads, even at relatively high temperatures
Pseudoplastic fracture behavior
Corrosion resistance and resistance to radiation
Very low creep
Production of high-purity grades possible

※ 0°corresponds to the alignment of the warp fibers or the axis of rotation of a winding mandrel

Carbon fibers

Basis:PAN, cellulose or pitch; various textile forms such as rovings, chopped fibers, yarns, felts, nonwovens, warp cloths, tapes, woven fabrics

phenolic and furan resins; pitches with different softening points for various uses

of fiber products and binders, eg into
- prepregs and laminates
- Impregnated felts
- Moulding compounds
- Wound components

Densification and hardening

Impregnation and rebaking Graphitizing

- Application of anti-oxidation finish
- Coating with silicon carbide
- Post-purification to a very low ash content
