NOVELTY - Thermal conductivity improvement involves mixing graphene oxide and absolute ethyl alcohol to form slurry, in which boron oxide is also added. The boron oxide is ground is anhydrous ethanol and deionized water, where the formed product is dried and ground to obtain boron-doped graphite powder. A middle phase asphalt is added in a certain amount of absolute ethyl alcohol to form a mixed slurry, where the formed slurry is mixed with the obtained boron-doped graphite. The obtained mixture is ground and dried to form middle phase asphalt. USE - Method for improving thermal conductivity of carbon-carbon composite material (claimed). ADVANTAGE - The method improves thermal conductivity of the carbon composite material having enhanced compatibility and bonding strength. DETAILED DESCRIPTION - Thermal conductivity improvement involves mixing graphene oxide and absolute ethyl alcohol to form slurry, in which boron oxide is also added. The boron oxide is ground is anhydrous ethanol and deionized water, where the formed product is dried and ground to obtain boron-doped graphite powder. A middle phase asphalt is added in a certain amount of absolute ethyl alcohol to form a mixed slurry, where the formed slurry is mixed with the obtained boron-doped graphite. The obtained mixture is ground and dried to form middle phase asphalt. The obtained middle phase asphalt and boron-doped graphite powder are mixed uniformly to obtain carbon/carbon composite material.
