The invention provides a production method of a novel prepreg material used for glue joint. In production of the novel prepreg material, one surface of carbon fiber is coated with a glue film used for prepreg so as to form a single surface glue film, and the other surface of carbon fiber is coated with a structure glue film at the same time, and the carbon fiber coated with the glue film used for prepreg and the structure glue film is subjected to preimpregnation so as to obtain the novel prepreg material. According to the production method, a resin A of the structure glue film and a resin B of the glue film used for prepreg are resins obtained via co-curing in a same system; the resin A is subjected to coating so as to obtain the structure glue film C; the resin B is subjected to coating so as to obtain the glue film D used for prepreg; and the novel prepreg material is obtained via preimpregnation of the structure glue film, the glue film used for prepreg, and carbon fiber at the same time. Combination of the structure glue film with prepreg is disclosed for the first time, in paving process, the novel prepreg material can be used for gluing sandwich structure materials directly, mould paving efficiency and performance of sandwich structure parts are improved, especially production efficiency of large sandwich structures can be doubled, and the original excellent performance of prepreg is ensured because preimpregnation of fiber with resin is carried out, and only the prepreg surface is coated with the structure glue film.
