The invention discloses a high-strength composite material rib and a preparation method thereof. The high-strength composite material rib is composed of a rib body and ribs. The rib main body is obtained by carrying out one-time curing molding on fibers infiltrated with resin; the rib main body is provided with a rough surface; and the ribs are obtained by winding prepreg yarns on the rib main body and then carrying out secondary curing molding. The fiber volume content of the rib main body is increased through two-time curing forming of the rib main body and the ribs, the bonding strength between the ribs and the rib main body is improved through the rough surface of the rib main body, the bonding strength between the ribs and the rib main body is further improved by combining hyperbranched epoxy resin and a silane coupling agent in the ribs, and the bonding strength between the ribs and the rib main body is further improved. Finally, the tensile strength and the bonding strength with concrete can be respectively improved by about 25% and 15% compared with those of a composite material rib produced in the prior art. And the comprehensive use performance of the composite material rib is effectively improved.
