Disclosed is a high-strength fiber reinforcement thin film sealing butt-joint structure universal for a high altitude airship. The high-strength fiber reinforcement thin film sealing butt-joint structure universal for the high altitude airship comprises left and right side butt-joint high-strength fiber reinforcement lamination composite universal skins, namely the left side skin and the right side skin, a middle reinforcement bearing layer, left side connecting sewing threads, right side connecting sewing threads, an inner side sealing film layer, a left side film layer sealing glue layer and a right side film layer sealing glue layer. The left side skin and the right side skin become the bottommost layers of the butt-joint structure. The middle reinforcement bearing layer, the left side skin and the right side skin are connected together through the left side connecting sewing threads and the right side connecting sewing threads. The inner side sealing film layer is the topmost layer of the butt-joint structure, covers connectors and then is in glue connection with the left side skin and the right side skin through the left side film layer sealing glue layer and the right side film layer sealing glue layer on the two sides, namely adhesive agents. According to the high-strength fiber reinforcement thin film sealing butt-joint structure universal for the high altitude airship, the technical difficult problems that in the butt-joint process of skin materials of the high altitude airship, the skin materials are high in welding intensity, and the helium leakage character is good are solved, the risk that the skin materials of the airship are torn and damaged at the butt joints of the skins in the high-altitude overpressure flying process of the high altitude airship is reduced, and the influence on the whole intensity of the airship in the skin high-frequency welding process is reduced.
