A carbon block with ultra-high anisotropy was produced from a commercial graphite paper as the thermal reinforcement and a thermosetting phenolic resin as the binder. Hot-pressing at a maximum temperature of 200°C was used to densify and integrate the graphite paper stacks. It has been found that the graphite paper blocks have high thermal conductivities in the paper direction and low ones perpendicular...
A carbon/carbon (C/C) composite with a thermal conductivity greater than 500W/mK was used as a heat-redistribution material in a new thermal protection system. Using this material, the temperature at the hot head of a model hypersonic aircraft re-entry cone was sharply decreased, which effectively reduced the thermal burden and protected the hot side from being destroyed.
A simple method for preparing the mesophase-pitch-based carbon foams at low pressures through prolonging the soaking time in the preparation process of the mesophase pitch was disclosed. The physical properties, morphologies and the crystal structure of the as-obtained foams were investigated. Bulk density of the resultant carbon foams cover a range 0.514–0.624g/cm 3 , under the preparation...
