Ihe mejupụtara carbon / carbon(nke a na-akpọ ya "C / C ma ọ bụ CFC") bụ ụdị ihe mejupụtara nke sitere na carbon ma mee ka carbon fiber na ngwaahịa ya sie ike (carbon fiber preform). Ọ nwere ma inertia nke carbon na ike dị elu nke eriri carbon. Ọ nwere ezigbo n'ibu Njirimara, okpomọkụ na-eguzogide, corrosion eguzogide, esemokwu damping na thermal na eletriki conductivity àgwà.

2. Nnukwu ịdị ọcha: nke a na-eme site na ntinye ikuku kemịkalụ n'okpuru ọnọdụ chlorination dị elu.
3. Nguzogide nbibi: elu ike, kọmpat elu, ezigbo ahụ.
4. Nguzogide corrosion: acid, alkali, nnu na organic reagents.
