摘　　要：随着国际形势不断变化,各国冲突加剧,国防力量的提升是保证国家稳定发展的必要条件,防弹装甲是其中的关键一环。无压烧结碳化硅陶瓷由于制备工艺简单,具有低密度、高硬度、高强度等特性,被广泛应用于防弹装甲领域,其硬度和断裂韧性的高低直接决定防弹性能的优劣。促进烧结致密化以及多相复合烧结等方式是提高无压烧结碳化硅陶瓷硬度和断裂韧性的关键。本文针对无压烧结碳化硅防弹陶瓷材料的烧结助剂、增韧方式、陶瓷装甲的复合形式等方面,总结了近年来无压烧结碳化硅防弹陶瓷材料的研究进展。As the international situation continues to change and conflicts in various countries intensify,improving national defense forces is a necessary condition to ensure the stable development of the country,and bulletproof armor is a key part of it.Pressureless sintered silicon carbide ceramics have been widely used in the field of bulletproof armor because of its simple preparation process and excellent mechanical properties of low density,high hardness and high strength.The hardness and fracture toughness of pressureless sintered silicon carbide bulletproof ceramics directly determine the quality of bulletproof performance.Promoting sintering densification and multi-phase composite sintering are the key ways to improve the hardness and fracture toughness of pressureless sintered silicon carbide ceramics.This study summarizes the research progress of pressureless sintered silicon carbide bulletproof ceramic materials in recent years,focusing on the sintering aids,toughening methods,composite form of pressureless sintered silicon carbide bulletproof ceramic materials.
