Progress of High-Thermal Conductivity Carbon/ Carbon Composites

Carbon/ carbon composites are attractive candidates for heat dissipation due to their high thermal conductivity,
low density, low dilatability and excellent mechanical properties. The paper summaries the research and
development of high-thermal conductive C/ C composites domestic and overseas, the thermophysical properties of C/ C
composites and the factors affecting on thermal conductivity are discussed. The thermal conductive mechanism of C/ C
composites,carbon fibers and matrix carbon are introduced, and the preparation and modification of C/ C composites
are also recommended.
