Abstract

The invention provides a high thermal conductivity carbon fiber cloth, which comprises a carbon fiber cloth and an attachment evenly distributed on the carbon fiber cloth. The attachment is a high thermal conductivity mixture, and includes micro-nano ceramic powder, a curing agent and adhesive resin, wherein, the weight percentage of the micro-nano ceramic powder is 20-50%, the weight percentage of the curing agent is 10-40%, and the weight percentage of adhesive resin is 30-60%. The high thermal conductivity carbon fiber cloth provided by the invention utilizes high thermal conductivity carbon fiber adhesive resin to replace the traditional insulating gel system so as to greatly increase the thermal conductivity between carbon fiber beams, if carbon fiber beam scattering, fracture and other phenomena occur, thermal energy can also be transmitted to other carbon fiber beams through the high thermal conductivity adhesive resin between carbon fiber, thus improving the heat conductivity coefficient, and also ensuring the directional properties of heat transfer. Therefore, the problems of low integral heat dissipation and poor reliability of carbon fiber cloth serving as a thermal conductivity product in the prior art can be solved.
