Thermoplastic polymer material as well as preparation method and application thereof

The invention relates to a thermoplastic polymer material as well as a preparation method and application thereof. The preparation method of the thermoplastic polymer material comprises the following steps: preparing a filament-shaped thermoplastic polymer into a three-dimensional structure arrangement body; preheating the three-dimensional structure arrangement body, wherein the preheating temperature is 0.4-0.5 time of the melting point of the thermoplastic polymer; pressing the preheated three-dimensional structure arrangement body to prepare a two-dimensional structure body; wherein the pressing temperature is 0.8-0.9 time of the melting point of the thermoplastic polymer; the pressing pressure is 0.1-1 time of the yield strength. According to the preparation method of the thermoplastic polymer material, the macroscopic and microscopic mechanical properties of the polymer material can be adjusted by adjusting the macroscopic and microscopic structures in the conversion process from the three-dimensional s
