Abstract

The invention discloses a self-luminous epoxy resin liquid, a preparation method of the self-luminous epoxy resin liquid, a self-luminous epoxy resin composite and a self-luminous carbon fiber prepreg. The self-luminous epoxy resin liquid is prepared from, by mass, 100 parts of epoxy resin, 5-15 parts of noctilucent powder, 0.01-0.15 part of a coupling agent, 0.001-0.005 part of an anti-settling agent, 1.2-2 parts of a dispersing agent, 3-9 parts of a dicyandiamide curing agent and 0.5-1.2 parts of an accelerant. According to the self-luminous epoxy resin liquid, the mixed resin, the dicyandiamide curing agent and the accelerant form an epoxy resin system, and an epoxy resin matrix obtained after curing has good mechanical performance and can serve as a resin matrix of the prepreg; the coupling agent, the anti-settling agent and the dispersing agent are in good compatibility with the system, all components achieve a synergistic effect, and thus the self-luminous epoxy resin liquid has high stability and wetting ability.
