Provided is a method for preparing high-performance carbon fiber composite materials derived from dicyclopentadiene, which introduces a dicyclopentadiene (DCPD) structure into carbon fiber to increase the dispersing capability of carbon fiber in dicyclopentadiene. As a result, the mechanical property and thermal stability of the polydicyclopentadiene material can be improved. Moreover, the method comprises the steps of: (1) preparing carbon fiber and acidifying the carbon fiber; (2) performing a sulfonyl chlorination reaction on the acidified carbon fiber; (3) performing an esterification reaction on the sulfonyl chlorinated carbon fiber and glycol to obtain modified carbon fiber as shown in expression (E); and (4) performing an esterification reaction on the modified carbon fiber of expression (E) and sulfonyl chlorination monomer of expression (B) to obtain modified carbon fiber as shown in expression (F).
