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.

    本发明公开了一种电梯安全钳楔块用复合材料、铜增强材料及其制备方法,该电梯安全钳楔块用复合材料,包括依次设置的第一多孔陶瓷预制体层、第二多孔陶瓷预制体层、第三多孔陶瓷预制体层、第四多孔陶瓷预制体层和第五多孔陶瓷预制体层;所述第一多孔陶瓷预制体层的气孔率、第二多孔陶瓷预制体层的气孔率、第三多孔陶瓷预制体层的气孔率、第四多孔陶瓷预制体层的气孔率和第五多孔陶瓷预制体层的气孔率相等。本发明利用陶瓷预制体层的特定层状结构和气孔率,赋予材料耐磨损和抗冲击性能。
