Abstract

The invention discloses a bulletproof ceramic chip with a cyclic structure and a bulletproof target plate as well as preparation methods of the bulletproof ceramic chip and the bulletproof target plate. The bulletproof ceramic chip is circular and is formed by nesting a central ceramic circular plate and multiple groups of rings, wherein the inner diameters of the multiple groups of rings are sequentially increased. The bulletproof target plate comprises the bulletproof ceramic chip with the cyclic structure and a PE back plate; the bulletproof ceramic chips are uniformly distributed on the PEback plate. According to the bulletproof ceramic chip disclosed by the invention, a cyclic structural design is introduced, so that the bulletproof performance of the bulletproof ceramic chip can beimproved; a certain amount of TiO2 and MgO powder is introduced into an Al2O3 powder so as to achieve low-temperature sintering; a certain amount of 3Y-ZrO2 is introduced so as to achieve the toughness; due to the existence of filling powder among the rings, the ceramic chip, ceramic rings and special parts can be bonded by sintering and the production efficiency of the bulletproof plate is favorably improved; the preparation methods disclosed by the invention have the characteristics of abundant raw material powder sources, low cost, simple production process and stable product quality.
