Thermoplastic fiber enhanced composite material, preparation method and application

The invention belongs to the field of a material, particularly relates to a thermoplastic fiber enhanced composite material, also relates to a preparation method and application of the material, and relates to a method for preparing a bag and suitcase casing by using the material as raw materials. The thermoplastic fiber enhanced composite material comprises a thermoplastic fiber fabric and thermoplastic resin. The thermoplastic fiber enhanced prepreg material/sheet material provided by the invention is used for preparing the bag and suitcase casing. Compared with a conventional hard suitcase body, the material has the advantages that the intensity and the anti-impact performance of the bag and suitcase can be greatly improved; the material intensity is greatly improved, so that the thickness of the casing can be reduced, and the self weight of the bag and suitcase can be reduced; the weight can be reduced by about 40 percent through being compared with that of the conventional hard suitcase; the anti-impact
