The invention discloses a high-temperature self-repair-type fiber-reinforcement epoxy composite material and a process for preparation, the process comprises adding microcapsule and accelerating agent which are evenly mixed into the basal body of epoxide resin, adding curing agent into the basal body of epoxide resin to evenly mix, infiltrating fiber-reinforcement reinforced materials with the mixture which is got, plying, finally, curing molding and getting high-temperature self-repair-type fiber-reinforcement epoxy composite material. When cracks are produced on the high-temperature self-repair-type fiber-reinforcement epoxy composite material of the invention because of forcing in the process of processing and employing, the cracks are extended to the built-in microcapsule, and the microcapsule wall is led to crack, liquid-state epoxide resin in the microcapsule is immediately released to fill into the cracks, the accelerating agent which is built in the basal body leads the liquid-state epoxide resin to be solidified under high temperature, thereby rebinding the cracks together, and the damage of the material is repaired, thereby keeping the mechanical properties of the epoxy composite material and prolonging the life span.
