Abstract: Carbon fiber reinforced plastics (CFRPs) is an important material that supports energy-saving and new energy fields. Particularly, in order to increase the demand for CFRPs in auto-motive applications, carbon fiber reinforced thermoplastics (CFRTPs) has been developed in the past decade. On the other hand, this industry needs to solve the problem of disposed CFRPs, and the development of recycling technology for CFRP has been active, and it is time to think more seriously about resource circulation. Furthermore, CFRTPs have some issues such as low impregnability because of high viscosity of thermoplastic, thermal stability. However, using polyetherimide (PEI) as the matrix polymer, issues of CFRTPs may be solved because of their rigid structure and solubility, and a circular-design CFRTPs can be also realized. Therefore, we report on the development of a circularly designed, high-quality CFRTPs made with polyeth-erimide (PEI).
