Layered bulletproof ceramic and preparation method thereof
The invention provides layered bulletproof ceramic and a preparation method thereof.The layered bulletproof ceramic comprises a high-hardness area and a high-toughness area which are sequentially arranged, the high-hardness area comprises first ceramic material layers and second ceramic material layers which are alternately stacked, and the high-toughness area comprises third ceramic material layers and fourth ceramic material layers which are alternately stacked; the preparation raw materials of the first ceramic material layer, the second ceramic material layer, the third ceramic material layer and the fourth ceramic material layer comprise silicon carbide and/or boron carbide, a carbon source and an auxiliary agent, and the total expansion coefficients of the first ceramic material layer and the second ceramic material layer are different; the total expansion coefficients of the third ceramic material layer and the fourth ceramic material layer are different. The layered bulletproof ceramic is subjected to functional gradient structure design and strong interface layered structure design at the same time, the double reinforcement effect is achieved, and the bulletproof performance of the material is greatly improved.
本发明提供了一种层状防弹陶瓷及其制备方法，层状防弹陶瓷包括依次设置的高硬度区和高韧性区，所述高硬度区包括交替层叠的第一陶瓷材料层和第二陶瓷材料层，所述高韧性区包括交替层叠的第三陶瓷材料层和第四陶瓷材料层，所述第一陶瓷材料层、所述第二陶瓷材料层、所述第三陶瓷材料层和所述第四陶瓷材料层的制备原料包括碳化硅和/或碳化硼、碳源和助剂，所述第一陶瓷材料层和所述第二陶瓷材料层的总膨胀系数不同，所述第三陶瓷材料层和所述第四陶瓷材料层的总膨胀系数不同。本发明同时对层状防弹陶瓷进行功能梯度结构设计和强界面层状结构设计，实现了双重强化效果，使材料防弹性能大幅提升。
