The invention discloses a composite material and a copper reinforced material for a wedge block of elevator safety tongs and a preparation method thereof. The composite material for the wedge block of the elevator safety tongs comprises a first porous ceramic prefabricated body layer, a second porous ceramic prefabricated body layer, a third porous ceramic prefabricated body layer, a fourth porous ceramic prefabricated body layer and a fifth porous ceramic prefabricated body layer which are sequentially arranged. The porosity of the first porous ceramic prefabricated body layer, the porosity of the second porous ceramic prefabricated body layer, the porosity of the third porous ceramic prefabricated body layer, the porosity of the fourth porous ceramic prefabricated body layer and the porosity of the fifth porous ceramic prefabricated body layer are equal. According to the composite material and the copper reinforced material for the wedge block of the elevator safety tongs and the preparation method thereof, the material is endowed with wear resistance and impact resistance by utilizing the specific layered structure and porosity of the ceramic prefabricated body layers.
