Abstract

The present invention relates to a technical field of new material, disclosing a carbon-carbon composite material and a preparation process and use thereof. The carbon-carbon composite material comprises a carbon fiber, a plurality of graphitized lamellae wrapping the carbon fiber, and non-carbon nanoparticles dispersed between the graphitized lamellae. The carbon-carbon composite material of the present invention comprises, on a microscopic scale, graphitized lamellae having a concentric circle structure. By means of this specific structure, the carbon fiber and the peripheral graphitized lamellae having the non-carbon nanoparticles dispersed therebetween, as well as the graphitized lamellae themselves, can be firmly bound, so that the obtained carbon-carbon composite material has better dimensional stability and electrical conductivity. Meanwhile, the carbon-carbon composite material of the present invention can have improved corrosion resistance, ablation resistance, temperature-resistance and sealing performance and/or electrochemical activity.
