This work innovatively proposed a micro-controlled carbon fiber (CF) energy to achieve the rapid curing of carbon fiber reinforced composites (CFRC). Compared with the traditional curing process, this process controlled the thin layer coated with CF bundles, explored the influence law of cross-linking curing of the CFRC with different power (current, voltage) and drag speed, and regulated the optimal process parameters. The results showed that the micro-controlled energy in the CF had an obvious effect on the curing of the CFRC. The curing degree first increased and then decreased with increasing power. Meanwhile, the effect of increasing drag speed on different viscous state was studied, which resulted in the different effects on the mechanical properties of the CFRC. In addition, the energy in the CF was micro-differentiated to construct the energy space, and the energy model in the curing process of the CFRC was proposed. Finally, it was proved that the CF spline curing process using this technology saved 95% time compared to traditional curing process, and it opened up a new idea for the large-scale preparation of the CFRC.
