Abstract: Owing to their numerous merits, carbon fiber reinforced thermoplastic composites (CRTP) have drawn extensive attention in many fields such as aerospace, rail transportation, military industry, wind power and et al. In this paper, the research progress in recent years on the preparation technology of CRTP in the world is summarized, and is mainly described from three aspects: The preparation technology of prepreg, surface modification technology of carbon fiber (CF) and processing technology of CRTP. Furthermore, the merit and demerit of different preparation technologies of prepreg, surface modification technologies of CF and processing technologies of CRTP, as well as the influence on the properties of the prepared CRTP, are introduced in detail. In the end, the development direction of preparation technology of prepreg, surface modification technology of CF and processing technology of CRTP is prospected.
