Abstract: A preparation method and a product of thermoplastic carbon fiber fabric prepreg are provided. The preparation method includes: covering a thermoplastic polyimide non-woven fabric on a carbon fiber fabric to obtain a laminated structure, pressing the laminated structure, then spraying polyphenylene sulfide nanoparticles onto the thermoplastic polyimide non-woven fabric, and performing a two-stage hot melting preparation process which includes: in a first stage, heating up to make the polyphenylene sulfide nanoparticles be melted and infiltrate and keeping a hot melting time of 5-10 min; and in a second stage, heating up to make the thermoplastic polyimide non-woven fabric be melted and infiltrate into the carbon fiber fabric and cooling down after a duration of heat preservation to prepare the thermoplastic carbon fiber fabric prepreg. The thermoplastic carbon fiber fabric prepreg prepared by the two-stage hot melting has high strength and may be stored for a long period.
