The invention discloses a carbon fiber skin structure. A carbon fiber skin is provided with an embedding part which is embedded in a metal matrix, and the carbon fiber skin is fixed together with the metal matrix through a bolt; the bolt is inserted in advance when the carbon fiber skin is prepared; and a nut matched with the bolt is arranged at the inner side of the metal matrix. The carbon fiber skin structure has the advantages that because the fixed bolt is inserted in advance when the carbon fiber skin is prepared, the breakage of the carbon fiber can be avoided, and thus the strength of the carbon fiber skin is ensured; and compared with other modes, such as a mode of fixing the carbon fiber skin with a base together by adopting a riveting method, during riveting, the breakage of the carbon fiber is certainly caused, and thus the strength of the skin is reduced.
