摘要： A composite container includes a barrel (10), a bottom cover (20), and a top cover (30). The barrel is formed by thermoforming of a rolled-up first plate (100) composed of laminated prepregs (100'). The bottom cover is formed by thermoforming of a second plate (200) composed of laminated prepregs. The top cover is formed by thermoforming of a third plate (300) composed of laminated prepregs. The bottom cover includes a first bottom (21) and a first flange (22). The top cover includes a second bottom (31) and a second flange (32). The second bottom is formed with a through hole (33). The bottom cover and the top cover are arranged at two ends of the barrel respectively, and the first flange and the second flange are positioned to the peripheral wall of the barrel by thermoforming.
