DETAILED DESCRIPTION
[0016] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.
[0017] like Figure 1-3 As shown, the utility model provides a technical solution: a high-speed railway carriage floor with thermoplastic fiber reinforced composite material, comprising a substrate layer 1, a sound absorbing mechanism 2 is arranged on the substrate layer 1, the sound absorbing mechanism 2 comprises a sound absorbing board 21, the sound absorbing board 21 is arranged on the substrate layer 1, the sound absorbing board 21 is connected to the sound insulation layer 3, a cavity 23 is opened in the sound absorbing board 21, and two sound absorbing cottons 22 are arranged in the cavity 23. By arranging the sound insulation layer 3, the sound absorbing board 21, the cavity 23 and the sound absorbing cotton 22, the propagation path of noise can be weakened and blocked under the mutual cooperation of the sound insulation layer 3, the sound absorbing board 21, the cavity 23 and the sound absorbing cotton 22, so as to achieve a double sound insulation effect, and the shape of the sound absorbing board 21 is set to be rectangular.
[0018] A sound-absorbing mechanism 2 is provided with a sound-insulating layer 3, and a reinforcing mechanism 4 is provided on the sound-insulating layer 3. The reinforcing mechanism 4 includes two thermoplastic fiber reinforced composite material layers 41, and the thermoplastic fiber reinforced composite material layer 41 is connected to the flame-retardant layer 5, and the thermoplastic fiber reinforced composite material layer 41 is connected to the sound-insulating layer 3. The inner sides of the two thermoplastic fiber reinforced composite material layers 41 are connected to the same fiberboard layer 42. By arranging the thermoplastic fiber reinforced composite material layer 41 and the fiberboard layer 42, under the mutual cooperation of the thermoplastic fiber reinforced composite material layer 41 and the fiberboard layer 42, the strength and compression resistance of the carriage floor can be improved. A flame-retardant layer 5 is provided on the reinforcing mechanism 4. By arranging the flame-retardant layer 5, the flame-retardant layer 5 has good flame-retardant properties and can flame-retard the floor surface layer 6 after burning. A floor surface layer 6 is provided on the flame-retardant layer 5, and an epoxy resin wear-resistant layer 7 is provided on the floor surface layer 6. By arranging the epoxy resin wear-resistant layer 7, the epoxy resin wear-resistant layer 7 can provide good wear-resistant protection for the floor surface layer 6.
[0019] The working principle of the utility model is:

The provision of the thermoplastic fiber reinforced composite material layer 41 and the fiberboard layer 42 improves the overall structural strength and compression resistance of the vehicle floor, thereby improving the availability of the vehicle floor.
