The invention relates to a room-temperature rapid self-repairing composite material based on microencapsulated epoxy resin and a super-strong-acid curing agent. According to the room-temperature rapid self-repairing composite material, a repairing system is formed by epoxy resin microcapsules and super-strong-acid curing agent microcapsules, and an instant-damage-instant-repair effect on thermosetting resin, such as epoxy resin, can be exerted at room temperature; epoxy resin and super-strong acid are respectively microencapsulated, and then, the two kinds of microcapsules are compounded into a thermosetting resin matrix, so as to prepare the self-repairing composite material which has rapid self-repair capability at room temperature; when the composite material is damaged (such as impact damage, fatigue microcrack and the like), the microcapsules rupture and release a repairing agent, epoxy resin is subjected to fast curing reaction when epoxy resin encounters to super-strong acid, and ...
