为了获得具有良好防弹性能的材料，采用热压和真空渗铝两步法获得了B4C/Al-B4C双层结构复合材料。在铝渗透之前，两层预制件的 B4C 多孔层看起来像互连毛细管的三维网络。对于 B4C 陶瓷层，在铝渗透之前和/或之后，微观结构没有表现出明显的变化。两层复合材料表现出比B4C材料更高的断裂韧性和比B4C-Al材料更高的综合硬度。 (C) 2013 Elsevier Ltd. 保留所有权利。
In order to obtain a material with a promising bulletproof performance, a two-layer structure composite consisting of B4C/Al-B4C was obtained using a two-step method for both hot pressing and infiltration aluminum in vacuum. Before aluminum infiltration the B4C porous layer of the two-layer preform looked like a three-dimensional network of interconnected capillaries. For the B4C ceramics layer the microstructure showed no apparent change before and/or after aluminum infiltration. The two-layer composite showed improved fracture toughness than that of B4C material and higher comprehensive hardness than that of B4C-Al material. (C) 2013 Elsevier Ltd. All rights reserved.
