The B4C matrix composite intended for armor applications still presents restrictions, such as low sintering density, production of large parts and inherited brittleness. Herein, research on this topic is discussed in detail. First, the material outlook of armor applications is organized from the development of composite armor and ceramic materials for armor to the B4C matrix composite and reactive-sintering method. In the second section, the technologies are reviewed for reactive pressureless sintering, reactive hot-pressing sintering, reactive discharge plasma sintering and self-propagating high-temperature sintering. Thereafter, our previous works on the TiB2/SiC/B4C composite and laminated Ti/B4C composite are employed to illustrate their microstructural evolution, phase transformation and fracture model. These studies provide a potential method for producing tough and high-strength ceramic composites for armor application. In the final section, the mechanism, evaluation method and influencing factors of anti-penetration for ceramic armor and B4C matrix composite are reviewed.

用于装甲应用的反应烧结 B4C 基复合材料

用于装甲应用的 B4C 基复合材料仍然存在限制，例如低烧结密度、大零件的生产和继承的脆性。在此，对这一课题的研究进行了详细讨论。首先，装甲应用的材料前景从复合装甲和装甲陶瓷材料的发展到B4C基复合材料和反应烧结方法的发展。第二部分综述了反应无压烧结、反应热压烧结、反应放电等离子烧结和自蔓延高温烧结技术。此后，我们之前在 TiB2/SiC/B4C 复合材料和层压 Ti/B4C 复合材料上的工作被用来说明它们的微观结构演变、相变和断裂模型。这些研究为生产用于装甲应用的坚韧和高强度陶瓷复合材料提供了一种潜在的方法。最后，综述了陶瓷装甲和B4C基复合材料的抗渗透机理、评价方法和影响因素。
