Composite material for marine transportation container as well as preparation method and application of composite material

The invention discloses a composite material for a marine transportation container and a preparation method and application thereof, the composite material comprises the following materials: PAN precursor, nylon and glass fiber, and the ratio of the PAN precursor to the nylon to the glass fiber is 3: 2. According to the composite material for the marine transportation container, the preparation method and the application of the composite material, the method is simple in process and high in operability, the forming quality and the size precision control requirement of the composite material can be effectively guaranteed, the phenomenon of poor precision caused by fuzzing can be prevented when carbon fibers are prepared, and the service life of the composite material is prolonged. After sizing treatment, the surface property of the carbon fiber can be well improved, a layer of film is formed on the surface of the carbon filament after sizing, so that the carbon filament is good in bundling property, improved i
