The invention provides bio-based copolymerized nylon resin and a preparation method thereof, and a bio-based copolymerized nylon composite material and a preparation method and application thereof, and belongs to the technical field of nylon resin and composite materials thereof. The water absorption of the polyamide material is mainly caused by the action of polar amido bonds and water molecules, the dodecanedioic acid adopted by the invention has longer carbon chains and lower amido density, the water absorption rate of the material is lower, and the barrier property to water is better; meanwhile, the carbon chain is longer, the toughness of the material is better, and the puncture resistance and the fatigue resistance are both in direct proportion to the toughness of the material. Therefore, the bio-based copolymerized nylon composite material prepared by the preparation method disclosed by the invention is excellent in barrier property, puncture resistance and fatigue resistance, can be widely applied to
