The invention provides a composite repair material which facilitates surgical operation and realizes quick defect nerve bridging and composition, preparation and application of a stent made of the composite repair material. The composite repair material consists of a fibroin layer, a collagen layer and a high-molecular polymer layer which are sequentially arranged, and during application, the composite repair material is folded or wound to form the nerve bridging stent taking the fibroin layer as the inner layer, the collagen layer as the middle layer and the high-molecular polymer as the outer layer. The composite repair material and the stent made of the composite repair material adopt the layered arrangement and a specific three-dimensional design to bring the advantages of various repair materials into full play, and meanwhile, make up for the deficiencies of the various repair materials. During surgical operation, only suturing or bonding anastomosis of epineurium is required but not suturing of perineurium, so that the operation time of a defect nerve bridging operation is greatly shortened, the operation technical difficulty is lowered, and the security is improved.
