Zusammenfassung:	The invention relates to a preparation method for a carbon fiber reinforced polyimide (PI) composite material. According to the method, a concentrated nitric acid oxidation and polyimide cladding composite method is adopted to perform surface modification on chopped carbon fiber (CF), so that the mechanical property of the CF reinforced thermoplastic polyimide composite material (CF/TPI) is improved.
